How to maximize the life of your Myron L meter’s pH or pH/ORP sensor
Your meter uses a general-purpose glass pH sensor. This glass sensor may be used in most applications.
To ensure maximum life of your pH meter, read the following procedures. It is the experience of the repair technicians that 90% of all premature pH sensor failures can be prevented with a few maintenance procedures.
The following procedures should be performed after using your meter, or if you plan to store your meter for an extended period of time.
1. The pH sensor well (fig 1) must be filled with storage solution (preferred) or pH buffer 4, or tap water with table salt added and its protective cap (with foam insert) firmly installed.
Failure to do so will:
• Allow the glass membrane to dry out. A dehydrated glass membrane will not produce the necessary “Gel layer” on the sensor surface, which is essential to allow the exchange of hydrogen ions (measure pH).
• Allow airborne contaminants to settle on the glass membrane surface. Once contaminants dry onto the surface of the glass membrane, it will inhibit the transfer of hydrogen ions. (See factory approved cleaning process below.)
• Allow the reference junction to dry out. The reference junction material is usually a wick or fiber type material that completes the electrical circuit between the reference electrode cell and the solution being tested. Dehydration causes the reference solution to leach out of the electrode cavity, and form crystals in the junction. This is normally referred to as the “Bridging effect”.
Repeated dehydration of the pH or pH/ORP sensor will cause the instrument to have a slower response time, and be more difficult to calibrate. Dehydration will significantly reduce the normal service life of the sensor.
2. Store spare pH or pH/ORP sensors in a refrigerator. “Do not Freeze”. Take proper precautions not to allow the temperature to fall below freezing. This will cause the solution to expand and may damage the electrodes inside the sensor. Storage in a refrigerated environment will slow the evaporation of the storage solution, but not prevent evaporation. Always inspect and replace storage solution in spare sensor well on a regular basis.
Note: When using storage solution, it is common for white crystal formations to form around the seal of the pH sensor well and protective cap; this is a normal occurrence as the solution evaporates. Never store the sensor in high purity water (distilled or de-ionized).
Approved factory cleaning process for the pH sensor
During the normal use of your Myron L meter, you must clean your pH sensor bulb. The cleaning is necessary to eliminate the deposits of organic or inorganic contaminates left on the sensor from the solutions being tested. If you think your meter is inaccurate, or the display value drifts, or the response is slow and sluggish, perform the following tests.
Rinse the sensor well (three times) and fill with pH buffer 4 solution. If the pH continues to drift below the pH 4 level (i.e. 3, 2, or 1) repeat the test using buffer 10. If the pH level drifts beyond the pH level of 10 (i.e. 11, 12 etc.) the cleaning procedure outlined below may increase the performance and accuracy of your meter.
While performing the above tests, if the pH levels of the buffer solutions 4 and 10 actually drift towards pH 7, this is an indication that the pH sensor is damaged and needs to be replaced.
Caution: Wear proper eye protection and gloves during the following cleaning procedures.
Try the following to clean and recover the pH or pH/ORP sensors.
NOTE: Not all pH or pH/ORP sensors can be recovered.
1. Fill the pH/ORP sensor well with 100% Isopropyl alcohol. If not available use additive- free rubbing alcohol (70%). This will remove any oils.
2. Allow the sensor to soak for 10 minutes.
3. Rinse with RO or DI water.
4. Rinse the sensor well (three times) and fill
with storage or pH buffer 4 solution. Replace the protective cap and allow the sensor to recover overnight.
5. Re-calibrate the instrument according to the operations manual. If the instrument fails to calibrate properly, continue to the next step.
If the above procedure does not recover the pH sensor function, perform the following:
1. Fill the pH or pH/ORP sensor well with a hot salt solution 60°C (140°F) potassium chloride (KCI preferred) or hot tap water with table salt (NaCl). Allow the solution to cool.
2. Re-calibrate the instrument according to the operations manual. If the meter doesn’t calibrate properly, the pH or pH/ORP sensor must be replaced.
*CAUTION: If you do not use your Myron L meter on a regular basis, the storage solution in the pH or pH/ORP sensor well will evaporate over time and must be replenished. To prevent premature pH glass sensor failure, we suggest a preventative maintenance program. Failure to do so could void the factory warranty. The use of liquids containing high levels of solvents, such as acetone, xylene, and chlorinated hydrocarbons, or other harsh chemicals in your Myron L meter is not recommended.

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!

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.
