Quick, Accurate Readings April 28, 2014

Reviewer: Manjit M, Project Engineer from UAE

Me & all my team uses ULTRAMETER II almost daily. It’s a great piece of equipment for Quick Accurate Readings. This handheld device is very easy to use & calibrate. Many times I use the hand held device as standard reference for my online meters, Another attractive part is the durability of the equipment – it will last for quite good period of time. Myron L products are undoubtedly reliable

Great Product, One of the Best! April 27, 2014

Reviewer: Env. Tech, Academic/Professional Researcher from California

I use this handheld many times each day. We have at least 3 on site at all times for regulatory purposes. I get accurate readings all the time in many types of water. It calibrates easier than any other handheld i have ever worked with. I keep these locked up in my office each night, because i have found over the years that leaving them in my vehicle during extremely cold conditions, or in direct sun light on hot days damages or shortens the life. I have tried several other handhelds because of a cheaper price, but none lasted more than a few months in these harsh conditions. I use these for Groundwater, Title 27 Ponds, wastewaters, fresh water, concentrated waters, and prodcut waters. I can use this one handheld for all of my monitoring.
LOVE IT!

Anyone and everyone who is responsible for operating and maintaining a swimming pool or spa has to test, monitor, and control complex, interdependent chemical factors that affect the quality of water bathers are immersed in. Additionally, aquatic facilities operators must be familiar with all laws, regulations, and guidelines governing what these parameters should be.

Why? Because the worst breeding ground for any kind of microorganism is a warm (enough) stagnant pool of water. People plus stagnant water equals morbid illness. That’s why pools have to be circulated, filtered, and sanitized – with any number of chemicals or methods, but most frequently with chlorine compounds. However, adding chemicals that kill the bad microorganisms can also make the water uncomfortable, and in some cases unsafe, for swimmers. Additionally, if all the chemical factors of the water are not controlled, the very structures and equipment that hold the water and keep it clean are ruined.

So the pool professional must perform a delicate balancing act with all the factors that affect both the health and comfort of bathers and the equipment and structures that support this. Both water balance – or mineral saturation control – and sanitizer levels must constantly be maintained. This is achieved by measuring pertinent water quality factors and adding chemicals or water to keep the factors within acceptable parameters.

WATER BALANCE

Water is constantly changing. Anything and everything directly and indirectly affects the relationship of its chemical parameters to each other: sunlight, wind, rain, oil, dirt, cosmetics, other bodily wastes, and any chemicals you add to it. Balanced water not only keeps swimmers comfortable, but also protects the pool shell, plumbing, and all other related equipment from damage by etching or build-up and stains.

The pool professional is already well acquainted with pH, Total Alkalinity (TA), and Calcium Hardness (CH); along with Total Dissolved Solids (TDS) and Temperature, these are the factors that influence water balance. Water that is in balance is neither aggressive nor oversaturated.

Aggressive water lacks sufficient calcium to saturate the water, so it is hungry for more. It will eat anything it comes into contact with to fill its need, including the walls of your pool or spa or the equipment it touches. Over-saturated water cannot hold any more minerals, so dissolved minerals come out of solution and form scale on pool and equipment surfaces.

The pH of pool water is critical to the effectiveness of the sanitizer as well as the water balance. pH is determined by the concentration of Hydrogen ions in a specific volume of water. It is measured on a scale of 0-14, 0-7 being acidic and 7-14 being basic.

You must maintain the pH of the water at a level that assures the sanitizer works effectively and at the same time protects the pool shell and equipment from corrosion or scaling and the bathers from discomfort or irritation. If the pH is too high, the water is out of balance, and the sanitizer’s ability to work decreases. More and more sanitizer is then needed to maintain the proper level to kill off germs. Additionally, pH profoundly affects what and how much chemical must be added to control the balance. A pH of between *7.2 – 7.6 is desirable in most cases.

*As one of the most important pool water balance and sanitation factors, pH should be checked hourly in most commercial pools. Even if you have an automatic chemical monitor/controller on your system, you need to double-check its readings with an independent pH test. With saltwater pools, pH level goes up fast, so you need to check it more often. Tests are available that require reagents and subjective evaluation of color depth and hue to judge their pH. But different users interpret these tests differently, and results can vary wildly.

Myron L’s POOLPRO™ gives instant lab-accurate, precise, easy-to-use, objective pH measurements, invaluable in correctly determining what and how much chemical to add to maintain water balance and effective sanitizer residuals.

Total Alkalinity (TA) is the sum of all the alkaline minerals in the water, primarily in bicarbonate form in swimming pools, but also as sodium, calcium, magnesium, and potassium carbonates and hydroxides, and affects pH directly through buffering. The greater the Total Alkalinity, the more stable the pH. *In general, TA should be maintained at 80 – 120 parts per million (ppm) for concrete pools to keep the pH stable. Maintaining a low TA not only causes pH bounce, but also corrosion and staining of pool walls and eye irritation. Maintaining a high TA causes over-stabilization of the water, creating high acid demands, formation of bicarbonate scale, and may result in the formation of white carbonate particles (suspended solids), which clouds the water. Reducing TA requires huge amounts of effort. So the best solution to TA problems is prevention through close monitoring and controlling. Myron L’s Alkalinity Test Kit comes with sodium hydrogen sulphate tablets and a mixing/measuring vial to determine alkalinity in parts per million.

The other water balance parameter pool professionals are most familiar with is Calcium Hardness (CH). CH is the calcium content of the water and is measured in parts per million. Low CH combined with a low pH and low TA significantly increases corrosivity of water. As the water becomes more aggressive, the solubility of calcium carbonate also increases. This means that plaster and marcite pool finishes will deteriorate quickly because calcium carbonate is a major component of both plaster and marcite. Low CH also leads to corrosion of metal components in the pool plant, particularly in heat exchangers. Calcium carbonate usually provides a protective film on the surface of copper heat exchangers and heat sinks. This thin layer prevents much water-to-metal interaction but does not adversely affect the heating process. Without this protective layer caused by low CH, heat exchangers and associated parts can be destroyed prematurely. Strangely enough, as water temperature increases, solubility of calcium carbonate decreases. *The recommended range for most pools is 200 – 400 ppm. Calcium hardness should be tested at least monthly and has the least significant effect on the water balance when compared to pH and TA.

Total Dissolved Solids (TDS) is the sum of all solids dissolved in water. If all the water in a swimming pool was allowed to evaporate, TDS would be what was left on the bottom of the pool – like the white deposits left in a boiling pot after all the water has evaporated. Some of this dissolved material includes hardness, alkalinity, cyanuric acid, chlorides, bromides, and algaecides. TDS also includes bather wastes, such as perspiration, urine, and others.

TDS is often confused with Total Suspended Solids (TSS). But TDS has no bearing on the turbidity, or cloudiness, of the water, as all the solids are truly in solution. It is TSS, or undissolved, suspended solids, present in or that precipitate out of the water that make the water cloudy.

High TDS levels do affect chlorine efficiency, algae growth, and aggressive water, but only minimally. TDS levels have the greatest bearing on bather comfort and water taste – a critical concern for commercial pool operators. At levels of over 5,000ppm, people can taste it. At over 10,000ppm bather towels are scratchy and mineral salts accumulate around the pool and equipment. Still some seawater pools comfortably operate with TDS levels of 32,000ppm or more.

As methods of sanitization have changed, high TDS levels have become more and more of a problem. *The best course of action is to monitor and control TDS by measuring levels and periodically draining and replacing some of your mature water with new, lower TDS tap water. This is a better option than waiting until you must drain and refill your pool, which is not allowed in some areas where water conservation is required by law. However, you can also decrease TDS with desalinization equipment as long as you compensate with Calcium Hardness. (Do not adjust water balance by moving pH beyond 7.8.)

Regardless, you do need to measure and compensate for TDS to get the most precise saturation index and adjust your pH and Calcium Hardness levels accordingly. *It is generally recommended that you adjust for TDS levels by subtracting one tenth of a saturation index unit (.1) for every 1,000ppm TDS over 1,000 to keep your water properly balanced. When TDS levels exceed 5,000ppm, it is recommended that you subtract half of a tenth, or one twentieth of unit (.05) per 1,000ppm. And as the TDS approaches that of seawater, the effect is negligible.

Hot tubs and spas have a more significant problem with TDS levels than pools. Because the swimmer load is relatively higher, more chemicals are added for super-chlorination and sudsing along with a higher concentration of bather wastes. The increased electrical conductance that high TDS water promotes can also result in electrolysis or galvanic corrosion. Every hot water pool operator should consider a TDS analyzer as a standard piece of equipment.

A TDS analyzer is required to balance the water of any pool or spa in the most precise way. Myron L’s POOLPRO and POOLMETER™ immediately display TDS levels to correctly calculate your water’s saturation index and to ensure you take corrective action before TDS gets out of hand.

Temperature is the last and least significant factor in maintaining water balance. As temperature increases, the water balance tends to become more basic and scale producing. Calcium carbonate becomes less soluble, causing it to precipitate out of solution. As temperature drops, water becomes more corrosive.

In addition to helping determine water balance, temperature also affects bather comfort, evaporation, chlorination, and algae growth (warmer temperatures encourage growth). Myron L’s POOLPRO also precisely measures temperature to one tenth of a degree at the same time any other parameter is measured.

The formula for determining water balance is called the Langlier Index, or Saturation Index. It is determined by the following formula:

SI= (pH + TF + CF + AF ) – 12.1

Where TF is the temperature, CF is Calcium Hardness, and AF is Total Alkalinity adjusted for temperature. 12.1 is the Total Dissolved Solids constant. Consult appropriate conversion charts to obtain the correct values for each variable.

– An index between -0.5 and +0.5 is acceptable pool water.
– An index of more than +0.5 is scale-forming.
– An index below -0.5 is corrosive.

pH, Total Alkalinity, and Calcium Hardness are the big three contributors to water balance. *Pool water will often be balanced if these factors are kept within the recommended ranges.

SANITATION

The most immediate concern of anyone monitoring and maintaining a pool is the effectiveness of the sanitizer – the germ-killer. There are many types of sanitizers, the most common being chlorine in swimming pools and bromine in hot tubs and spas. The effectiveness of the sanitizer is directly related to the pH and, to a lesser degree, the other factors influencing water balance.

To have true chemical control, you need to monitor both the sanitizer residual and the pH and use that information to chemically treat the water – that’s where ORP comes in. ORP indicates the ability of oxidizers to burn up organic matter in the water, which means your water is clean and sanitary. There are colorimetric tests used to determine the amount of effective sanitizer for chlorine and other elements, but none is as objective and precise in determining the total killing power of all sanitizers as ORP.

ORP stands for Oxidation Reduction Potential (or REDOX) of the water and is measured in millivolts (mV). The higher the ORP, the greater the killing power of all sanitizers, not just free chlorine, in the water. ORP is the only practical method available to monitor sanitizer effectiveness. Thus, every true system of automatic chemical control depends on ORP to work.

The required ORP for disinfection will vary slightly between disinfecting systems and is also dependent on the basic water supply potential, which must be assessed and taken into account when the control system is initialized. *650mV to 700 – 750mV is generally considered appropriate.

Electronic controllers can be inaccurate and inconsistent when confronted with certain unique water qualities, so it is critical to perform manual testing with separate instrumentation. *For automatic control dosing, it is generally recommended that you manually test pH and ORP prior to opening and then once during the day to confirm automatic readings.

*Samples for confirming automatic control dosing should be taken from a sample tap strategically located on the return line as close as possible to the probes in accordance with the manufacturer’s instructions. If manual and automatic readings consistently move further apart or closer together, you should investigate the reason for the difference.

ORP readings can only be obtained with an electronic instrument. Myron L’s POOLPRO provides the fastest, most precise, easy-to-use method of obtaining ORP readings to check the effectiveness of the sanitizer in any pool or spa. This is the best way to determine how safe your water is at any given moment.

SALTWATER SANITATION

A relatively new development, saltwater pools use regular salt, sodium chloride, to form chlorine with an electrical current much in the same way liquid bleach is made. As chlorine – the sanitizer – is made from the salt in the water, it is critical to maintain the salt concentration at the appropriate levels to produce an adequate level of sanitizer. It is even more important to test water parameters frequently in these types of pools and a spa, as saltwater does not have the ability to respond adequately to shock loadings (super-chlorination treatments).

Most saltwater chlorinators require a *2,500 – 3,000ppm salt concentration in the water (though some may require as high as 5,000-7,000ppm). This can barely be tasted, but provides enough salt for the system to produce the chlorine needed to sanitize the water.

(It is important to have a good stabilizer level – *30 – 50 ppm – in the pool, or the sunlight will burn up the chlorine. Without it, the saltwater system may not be able to keep up with the demand regardless of salt concentration.)

Taste and salt shortages are of little concern to seawater systems that maintain an average of 32,000ppm. In these high-salt environments, you need to beware of corrosion to system components that can distort salt level and other parameter readings.

Additionally, incorrect salt concentration readings can occur in any saltwater system. The monitoring/controlling components can and do fail or become scaled — sometimes giving a false low salt reading. Thus, you must test manually for salt concentration with separate instrumentation before adding salt.

You must also test salt concentration manually with separate instrumentation to re-calibrate your system. This is critical to system functioning and production of required chlorine. Myron L’s POOLPRO conveniently tests for salt concentration at the press of the button as a check against automatic controller systems that may have disabled equipment or need to be re-calibrated.

As you can see, there are many factors affecting the comfort and sanitation of pool and spa water and the functioning of the equipment and structures that hold it, and no one instrument or method can be used to determine ALL of them, but Myron L’s POOLPRO gives you the most precise and comprehensive water testing instrument in one easy-to-use, handheld waterproof unit. Where precision counts, we’ve got you covered.

RECORD KEEPING – What to do with all those measurements …

Now that you have the data, you have to correctly transcribe, evaluate, and report it to the proper government agencies, or at least archive it as permanent record of proper compliance to whatever regulations apply to your pool or spa. (As if sanitizing and balancing the chemistry of the water wasn’t enough.)

*It is recommended (by the World Health Organization and other entities) that data handling be done objectively and that data be recorded in a common format and in the most accurate way. Also, data should be stored in more than one permanent location and made available for future analysis. *Most municipalities require commercial aquatic facilities to keep permanent records onsite and available for inspection at any time.

*Myron L’s POOLPRO makes it easy to comply with data record requirements. The POOLPRO is an objective means to test ORP, pH, TDS, temperature and the mineral/salt content of any pool or spa. You just rinse and fill the cell cup by submerging the waterproof unit and press the button of the parameter you wish to measure. You immediately get a standard, numerical digital readout – no interpretation required – eliminating all subjectivity. Up to 100 date-time-stamped readings can be stored in memory and then later transferred directly to a computer using our BluDock™ accessory package. You just set the unit on the Bludock and download the data to the computer. The user never touches or tampers with the data, reducing the potential for human error in transcription. The data can then be imported into any program necessary for record-keeping and analysis. *The Bludock is the fastest, easiest, best way to keep records that comply with governing standards.

Myron L Company’s POOLPRO is SIMPLY the best.

*Consult your governing bodies for specific testing, chemical concentrations, and all other guidelines and requirements. The ranges suggested here are meant as general examples.
Myron L Company assumes no responsibility for lack of compliance to specific regulations governing the testing and control of parameters in your pool and/or spa.

Performs reliably for me every day April 27, 2014

Reviewer: Ron W., consultant from Huntington Beach CA
I purchased two Myron PT2 Ultrapens for pH and temperature monitoring in June this year and I use them 5 days a week without any problems whatsoever. I monitor pH and temperature on a Biotrickling filter foul air scrubber in a remote location and the Ultrapen performs reliably for me every day. I will be looking to Myron to purchase other instruments as the need arises.

The pH unit that works! April 13, 2014

Reviewer: Coree Coppinger from Milwaukee, WI, US
The other hand held meters varied in price from about 18.00 to 170.00, yet they preform the same: inaccurate, slow, leaked and turn itself off before the calculation was finished. All instructions were performed as noted by directions and videos.

A small field pH unit that was accurate and could be counted on. I relish in it’s simplicity and accuracy. The bottom rubber cap has a sponge inside of it to hold the storage solution, this is smart, although the push and twist is difficult with a flexible rubber cap. This could be better designed with a hard twist cap and a O RING in the inside of the cap. I am so happy to find a unit that preforms as it is supposed to, and is dead on with the solutions. The only thing to test next is how well it preforms with time. Yes this Myron L UltraPen PT2 is worth the money. After the ill fated experiences with the other brands being sold on the market you will find the price is much easier to swallow. It works and is accurate, that is all I ask!

Ultrapen PTBT1 and PTBT2

ULTRAPEN PTBT1 Conductivity/TDS/Salinity Pen

Bluetooth enabled Pocket Testers for use with Apple iOS 6 and iOS 7 mobile devices. The ULTRAPEN PTBT1 is designed to be extremely accurate, fast and simple to use in diverse water quality applications. Advanced features include the ability to select from 3 different solution types that model the characteristics of the most commonly encountered types of water; proprietary temperature compensation and TDS conversion algorithms; highly stable microprocessor-based circuitry; user-intuitive design; and waterproof housing. A true, one-handed instrument, the PTBT1 is easy to calibrate and easy to use. To take a measurement, you simply press a button then dip the pen in solution. Results display in seconds.

A free app takes advantage of Apple’s iOS graphical user interface to provide easy-to-read displays and a simple-to-use interface. The Bluetooth link means that there are no wires getting in the way when moving quickly between samples and that paired mobile devices can be held safely away from liquids.

Advanced features include: automatic temperature compensation; stable microprocessor-based circuitry; user-intuitive design and a rugged, waterproof housing.
The Ultrapen PTBT1 measures conductivity, total dissolved solids, salinity and temperature with three, selectable solution modes that model commonly encountered water types. The Ultrapen PTBT2 measures pH and temperature with one-, two- and three-point calibration options.
With the Ultrapen OS app, each Ultrapen PTBTx can be given a unique name stored in the Ultrapen’s memory so it is easily identifiable no matter what mobile device is used. Measurement locations can be programmed as GPS locations that are automatically selected when the user is close to a specific measurement local, or non-GPS locations, which are ideal for applications where the sample sites are too close together for the GPS to discriminate.
Through the app, items such as Ultrapen settings, sample temperatures, Ultrapen name and measurement locations can be saved to the mobile device’s memory. Records can be exported via the mobile device’s email function as either .csv, .xls, .xlsx formatted files or using a proprietary, encrypted format. Stored measurements can be sorted or filtered and then emailed or deleted without affecting other records stored in the memory.
The Ultrapen PTBT3 with ORP and temperature measurement, Ultrapen PTBT4 with free chlorine equivalent and temperature measurement, and an Android-compatible app are all coming soon.

ULTRAPEN – PTBT1
Another significant advantage to the PTBT1 is there are no bothersome wires connecting your mobile device to the sensors. Not only is it less hassle to move quickly from sample to sample, but the paired mobile device can be held safely away from the liquid samples being measured.


Using PTBT1 mobile app’s GUI:

• Each PTBT1 can be given a unique, user programmable, 14-character name that is stored in the microprocessor onboard the PTBT1 so that it is easily identifiable no matter what mobile device it is used with.

• Locations can be programmed into the application, either as GPS related locations that are automatically selected whenever the user is close to a specific measurement local, but also as non-GPS related locations. This non-GPS location feature is ideal for applications, such as laboratory environments, where the user might want to distinguish between sample sites that are too close to each other for the GPS to discriminate.

• Each measurement can be saved to the mobile device’s memory. Saved records include measurement data, sensor settings, the temperature, the pen name, and the location.

• Records can be exported via your mobile device’s email function as either .csv, MS Excel .xls or .xlsx formatted files or using Myron L’s .mlc, proprietary, secure and encrypted format.

• Stored measurements can be easily sorted and/or filtered, and emailed separately or deleted without affecting other records stored in the device’s memory.

The PTBT1 combine highly accurate measurement capabilities with the most up to date GUI interface and computing power to provide a powerful tool for both field and laboratory applications.

The Ultrameter III 9P Titration Kit allows for fast, accurate alkalinity, hardness & LSI titrations in the field.

The Ultrameter III 9P is based on the tried and tested design of the Ultrameter II 6P and measures conductivity, resistivity, TDS, pH, ORP, free chlorine and temperature quickly and accurately. The 9P also features new parameters that allow the user to perform titrations in the field. The Ultrameter III 9P has a unique method of performing alkalinity, hardness and LSI titrations that makes field monitoring fast and feasible.

How does it work?

The 9P titrations are based on conductometric titration methods that are possible with the 9P’s advanced conductivity cell and microprocessor based design. Titrations are chemically equivalent to standard methods using colorimetric techniques, but replace color change identification of equivalence points with changes in conductivity, thereby replacing a subjective, qualitative assessment with a quantitative one. This means the instrument determines the equivalence point instead of the user and the method of analyzing the equivalence point is objective, rather than subjective.

What is a conductometric titration?

A conductometric titration is performed just like a colorimetric titration, only the equivalence point is determined by a change in conductivity rather than a change in color. This is based on the fact that changes in ionic concentration that occur as constituents react with reagents change the electrical conductivity of the solution.

A simple example can be given of the titration of a strong acid with a strong base. The acid solution, before the addition of the base, has a very high conductance owing to the concentration and mobility of the small hydrogen ions.

With the addition of the base, the hydroxide reacts with the hydrogen to form water, thus reducing the hydrogen ion concentration and effectively lowering the conductivity of the solution. The conductivity continues to decrease until all the hydrogen ions are consumed in the reaction, but then sharply increases with the next addition of base, which contains highly conductive hydroxide ions. The solution conductivity then continues to increase with each base addition. The equivalence point in this example would be a clearly defined minimum point of lowest conductivity (see Figure 2).

Not all solutions will give a plot with an equivalence point that is as easy to distinguish as the sharp upturn found in a strong acid-base titration, however. The 9P plots several reagent additions beyond any changes in conductivity and matches the derived curve to the behavior of solutions of known concentration.

Is a conductometric titration a standard method?

(Standard method comparison to methods listed in the Standard Methods for the Examination of Water and Wastewater published by the American Public Health Assn., the American WaterWorks Assn. and the Water Environment Assn.)

Myron L’s conductometric titration methods are chemically equivalent to standard methods that use the same procedure, but with pH indicators. That means that they use the same reagents in the same sequence with the same theoretical approach. The difference lies in the 9P’s ability to determine the equivalence point based on numerical data, rather than subjective observation of a color change.

The alkalinity titration is modeled after standard method 2320. The sample is titrated with sulfuric acid and conductivity changes are recorded at each titration point.

The hardness titration is modeled after standard method 2340. To reduce the affects of high alkalinity in the form of bicarbonate, acid is first added to the sample. This shifts the bicarbonate toward carbonic acid, then carbon dioxide (reference the carbonic acid equilibrium), which is gassed off the sample. The sample is buffered above pH 10 (effectively pH 12) by the addition of sodium hydroxide. EDTA reagent is then added incrementally, with conductivity measured after each addition.

The LSI titration uses a simplified version of the thermodynamic equations for the determination of the scaling tendency of water developed in 1936 by Dr. Wilfred Langelier. The user simply titrates for alkalinity and hardness, then measures pH and temperature, and the 9P generates the saturation index value automatically.

Conductometric vs. Colorimetric

The benefits of determining the equivalence points by conductometric titrations are that the user does not have to interpret any results. The 9P does it for you using objective measurements. And the 9P is a faster method. For example, a typical colorimetric titration for hardness can take up to 30 drops of reagent, while the 9P method for the same concentration only requires six to eight drops. Colorimetric distinctions are sometimes hard to make, as well, especially when adding reagents drop by drop while trying to carefully observe the precise point at which the color changes—and that can lead to inaccurate data. This is especially true in colored or turbid solutions.

The conductometric method can also be used with very dilute solutions or for solutions for which there is no suitable indicator. The conductometric titration method gives you empirical results that are calculated for you, eliminating potential sources of error. And the measurements can be stored in memory for later data transfer using the optional U2CI software and bluDock Bluetooth hardware installed on the 9P . This makes data analysis and reporting seamless.

What else can the Ultrameter III 9P do?

Alkalinity, hardness, pH and temperature values used to compute the saturation index of a sample can be manipulated in the LSI Calculator function, allowing you to perform on the spot analysis of water balance scenarios. You can use historical or theoretical data to populate the required values in the calculator.

And the 9P titration kit comes with all required accessories, reagents, and calibration solutions (see Figure 6). Streamline your field testing with an Ultrameter III 9P from MyronLMeters, where you can save 10% when you order online.

DEIONIZED WATER APPLICATIONS: MyronLMeters.com

Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

THE DEIONIZATION PROCESS
The vast majority of dissolved impurities in modern water supplies are ions such as calcium, sodium, chlorides, etc. The deionization process removes ions from water via ion exchange. Positively charged ions (cations) and negatively charged ions (anions) are exchanged for hydrogen (H+) and hydroxyl (OH-) ions, respectively, due to the resin’s greater affinity for other ions. The ion exchange process occurs on the binding sites of the resin beads. Once depleted of exchange capacity, the resin bed is regenerated with concentrated acid and caustic which strips away accumulated ions through physical displacement, leaving hydrogen or hydroxyl ions in their place.

DEIONIZER TYPES
Deionizers exist in four basic forms: disposable cartridges, portable exchange tanks, automatic units, and continuous units. A two-bed system employs separate cation and anion resin beds. Mixed-bed deionizers utilize both resins in the same vessel. The highest quality water is produced by mixed-bed deionizers, while two-bed deionizers have a larger capacity. Continuous deionizers, mainly used in labs for polishing, do not require regeneration.

TESTING Dl WATER QUALITY
Water quality from deionizers varies with the type of resins used, feed water quality, flow, efficiency of regeneration, remaining capacity, etc. Because of these variables, it is critical in many Dl water applications to know the precise quality. Resistivity/ conductivity is the most convenient method for testing Dl water quality. Deionized pure water is a poor electrical conductor, having a resistivity of 18.2 million ohm-cm (18.2 megohm) and conductivity of 0.055 microsiemens. It is the amount of ionized substances (or salts) dissolved in the water which determines water’s ability to conduct electricity. Therefore, resistivity and its inverse, conductivity, are good general purpose quality parameters.

Because temperature dramatically affects the conductivity of water, conductivity measurements are internationally referenced to 25°C to allow for comparisons of different samples. With typical water supplies, temperature changes the conductivity an average of 2%/°C, which is relatively easy to compensate. Deionized water, however, is much more challenging to accurately measure since temperature effects can approach 10%/°C! Accurate automatic temperature compensation, therefore, is the “heart’ of any respectable instrument.

RECOMMENDED MYRON L METERS
Portable instruments are typically used to measure Dl water quality at points of use, pinpoint problems in a Dl system confirm monitor readings, and test the feed water to the system. The handheld Myron L meters have been the first choice of Dl water professionals for many years. For two-bed Dl systems, there are several usable models with displays in either microsiemens or ppm (parts per million) of total dissolved solids. The most versatile instruments for Dl water is the 4P or 6PFCE Ultrameter II™, which can measure both ultrapure mixedbed quality water and unpurified water. It should be noted that once Dl water leaves the piping, its resistivity will drop because the water absorbs dissolved carbon dioxide from the air. Measuring of ultrapure water with a hand-held instrument requires not only the right instrument, but the right technique to obtain accurate, repeatable readings. Myron L meters offer the accuracy and precision necessary for ultrapure water measurements.

Inline Monitor/controllers are generally used in the more demanding Dl water applications. Increased accuracy is realized since the degrading effect of carbon dioxide on high purity water is avoided by use of an in-line sensor (cell). This same degradation of ultrapure water is the reason there are no resistivity calibration standard solutions (as with conductivity instruments). Electronic sensor substitutes are normally used to calibrate resistivity Monitor/controllers.

Myron L Meters carries a variety of inline instruments, including resistivity Monitor/controllers designed specifically for Dl water. Seven resistivity ranges are available to suit any Dl water application: 0-20 megohm, 0-10 megohm, 0-5 megohm, 0-2 megohm, 0-1 megohm, 0-500 kilohm, and 0-200 kilohm. Temperature compensation is automatic and achieved via a dual thermistor circuit. Monitor/controller models contain an internal adjustable set point, piezo alarm connectors and a heavy-duty 10 amp relay circuit which can be used to control an alarm, valves, pump, etc. Available options include 4-20 milliamp output, 3 sensor input, 3 range capability and temperature. Internal electronic sensor substitutes are standard on all Monitor/controllers.

Sensors are available constructed in either 316 stainless steel or titanium. All sensors are provided with a 3/4″ MNPT polypropylene bushing and 10 ft./3 meters of cable. Optional PVDF or stainless steel bushings can be ordered, as well as longer cable lengths up to 100 ft./30 meters.
