MyronLMeters.com announces the arrival of a new product, the UltraPen PTBT1, Bluetooth enabled Pocket Tester for use with Apple iOS 6 and iOS 7 mobile devices, now in stock

Ultrapen PTBT1—Conductivity, Total Dissolved Solids (TDS), Salinity, and Temperature, with the ability to select from 3 different solution types that model the characteristics of the most commonly encountered types of water.

The Ultrapen PTBT1 is accurate, reliable and easy to use in many water quality applications. Advanced features include automatic temperature compensation; highly stable microprocessor based circuitry; user-intuitive design; and waterproof housing. The Ultrapen PTBT1 Pocket Tester is easy to calibrate and easy to use.

The Ultrapen PTBT1 Pocket Tester replaces the standard LCD display of most pen-type meters, with a Bluetooth BLE transceiver that transmits measurements to any paired Apple iOS 6 or iOS 7 mobile device. The readings are displayed in large, easy-to-read characters via a free App specifically designed to take full advantage of the Apple iOS Graphical User Interface (GUI).

Using the Ultrapen PTBT1 mobile app’s interface:

• 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 locations that are automatically selected whenever the user is close to a specific measurement locale, but also as non-GPS related locations. This non-GPS location feature is ideal for applications, such as laboratory environments, where there are sample sites 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 combines highly accurate measurement capabilities with the most up to date Graphical User interface and computing power to provide a powerful tool for both field and laboratory applications.

Average Customer Review: 5 of 5 | Total Reviews: 2

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!

Expert Manages Storm Water Discharge in Active Construction Sites With Ultrameter II 6P: MyronLMeters.com

Mike Alberson, an expert in storm water pollution prevention, uses the Myron L Ultrameter II 6P to meet new and existing state and federal requirements for storm water monitoring. He checks for the presence of pollutants by testing the levels of total dissolved solids (TDS) and conductivity. He also tests storm water pH levels in accordance with NPDES guidelines implemented in California in 2010 that mandate pH testing for all Risk Level 2 and 3 sites.

Though TDS and conductivity do not indicate the presence of any specific contaminant, monitoring these parameters is a good way to determine an increase in the concentration of dissolved chemical constituents generally. High conductivity or TDS levels are a red flag to Alberson to investigate potential sources of pollution.

Chemicals used in landscaping, such as herbicides, pesticides and fertilizers, as well as materials such as cement, can all potentially dissolve into storm water runoff. Additionally, acidic or basic pollutants impact the quality of water by altering the pH of the runoff. Monitoring is required because altering the pH alters the types and amounts of all chemical constituents in runoff and, thereby, its toxicity. Changes in pH also impact the ecosystem directly when they exceed the narrow range required by biota to live in the receiving waters. The new California NPDES requirements have set a pH range limit of 6.5 to 8.5 pH Units

The State Water Quality Board’s overall goal in implementing increased monitoring and reporting requirements is to evaluate the effectiveness of Best Management Practices (BMPs) on effluent pollution and the impact that construction activities have on receiving waters. Developers and inspectors like Alberson are continually challenged with preventing potential pollutants from leaving the project sites, and when that happens, they need to remediate any adverse affects on the environment.

As a prerequisite to construction, the Developer of Plan must generate and gain approval of BMPs and Storm Water Pollution Prevention Plans (SWPPPs) which take into account the nature of the project’s building schedule, phasing of the project, building materials, the projected rainfall, the percentage of impervious cover on the project and the impact that potential storm water runoff could have on receiving waters.  The plans must also address the required monitoring and critical indicators of specific pollutants projected to discharge from the project site.

The site storm water inspector has to ensure that the necessary BMPs are implemented throughout the length of the project, as defined by the project SWPPP plan, which addresses project-specific site conditions and risk level determinations.  Alberson uses the meter frequently on Barnhart Balfour Beatty projects as most fall into a category of Risk Level 2, which now requires pH monitoring along during a rain event of 0.5 in. or more.

New California requirements have required all SWPPP developers and inspectors to be certified by the state since Sept. 2, 2011 via a special course given by designated State Trainers of Record (TOR). Alberson is designated as a TOR and offers California’s new Qualified SWPPP Practitioner and Qualified SWPPP Developers courses.

As a trainer, Alberson passes on knowledge gained from his own experience. Through the years, he has seen inspectors send water samples off to laboratories for analysis, the results of which would not be known for up to two weeks. In addition, the pH of these samples would change in the time it took to get the samples to the labs for analysis. Alberson now trains developers and inspectors to use the Myron L Ultrameter II to immediately measure pH, thereby ensuring storm water runoff on project sites is precisely monitored for potential pollutants in real time.

In his own work as an inspector, Alberson has used the Myron L Ultrameter II to respond to potential pollution issues as they arise. For example, at Barnhart Balfour Beatty’s Otay Ranch Village #6 Elementary School project in Otay Mesa, Calif., he developed a remediation solution that prevented environmental contamination from high pH runoff resulting from a required lime treatment of the campus soil. By performing onsite testing following a rain event, Alberson was able to determine the potential runoff had a pH level of 12.5.  He decided to immediately utilize a retention pond with carbon dioxide percolation control techniques. His remediation tactic worked using the meter to continuously monitor the pH until it was at a level acceptable for release into the receiving waters.

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.

The more conductive ions that are present, the more electricity can be conducted by the water. This measurement is expressed in microsiemens per centimeter (µS/cm) at 25º Celsius. Myron L Meters carries a complete line of conductivity meters, including the Ultrameter II 4P.

Resistivity is the inverse of conductivity. Electrical conductivity is a measure of water’s resistance to an electric current. Water itself has a weak electrical conductivity. Electric current is transported in water by dissolved ions, making conductivity measurement a quick and reliable way to monitor the total amount of ionic contaminants in water. Myron L Meters carries a complete line of resistivity meters, including inline monitor/controllers like the 753II Resistivity Digital Monitor/Controller.

Total Dissolved Solids (TDS) is also a measurement of the amount of dissolved minerals in the water. In this instance they would be called solids in solution. The quantity of dissolved solids in the solution is directly proportional to the conductivity. In this case, conductivity is the measurement but it is used to estimate TDS. It is measured with a conductivity meter but is reported as TDS in parts per million (ppm), via a complex algorithm. Myron L Meters carries a complete line of TDS meters, including the Ultrapen PT1.

pH is a measure of the concentration of hydrogen ions in the water, indicating the acidity or alkalinity of the water. On the pH scale of 0-14, a reading of 7 is considered to be neutral. Readings below 7 indicate acidic conditions, while readings above 7 indicate the water is alkaline or basic. Naturally occurring fresh waters have a pH range between 6 and 8. Myron L Meters carries a complete line of pH meters, including the Ultrapen PT2

Temperature is expressed in degrees Celsius (C) or Fahrenheit (F). Most digital handheld Myron L Meters include a temperature function.



Oxidation reduction potential (ORP)can correlate millivolt readings to the sanitization strength of the water. Microbes can cause corrosion, fouling, and disease, and oxidizing biocides are usually used to keep microbial levels under control. ORP is expressed in millivolts (mV). Myron L Meters carries a complete line of ORP meters, including the Ultrapen PT3

Free Chlorine refers to both hypochlorous acid (HOCl) and the hypochlorite (OCl–) ion or bleach, and is commonly added to water systems for disinfection. Free chlorine is typically measured in drinking water disinfection systems to find whether the water system contains enough disinfectant.  Myron L Meters Ultrameter II 6PFCe and Ultrapen PT4 can both be used to measure free chlorine.

Salinity is simply a measure of the amount of salts dissolved in water, a measurement useful to pool service technicians and others.  You can measure salinity with a Myron L Pool Pro PS6.

Alkalinity is a measure of the capacity of water or any solution to neutralize or “buffer” acids. This measure of acid-neutralizing capacity is important in figuring out how “buffered” the water is against sudden changes in pH. Alkalinity is a titration function of the Ultrameter III 9PTKA.

Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals.  As water moves through soil and rock, it dissolves very small amounts of minerals and holds them in solution. Calcium and magnesium dissolved in water are the two most common minerals that make water “hard.” Hardness is a titration function of the Ultrameter III 9PTKA.

LSI or Langelier Saturation Index helps you determine the scaling potential of water. LSI is a calculated number used to predict the calcium carbonate stability of water. It indicates whether the water will precipitate, dissolve, or be in equilibrium with calcium carbonate. LSI is a titration function of the Ultrameter III 9PTKA.
