NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.

Milwaukee Instruments manufactures electrochemical instrumentation and solutions for water analysis under the Milwaukee and Martini brands. The company, founded in 1998, is headquartered in Rocky Mount, NC.

Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

What’s in the Box?

  • Meter 35423-10
  • Integral sensor

*Age of the solutions, storing of the solutions, contamination of the solutions can all affect readings.

*Accuracy depends on caliberation standards, type of water or how the meter is stored.

*Are you testing RO water, distilled water, de-ionized water?  Over time these liquids will drain the electrode of IONS and render the meter useless. Water of this type has no IONS so the salt solution within the probe will migrate out of the pH probe into the water. Naturally IONS move from high concentration to low concentration to create equilibrium. You can always use a TDS meter to test the water, you should get a reading around 0.00ppm. 

*
How should the Testrs being stored?  In OAKTON storage solution. The storage solution contains the same liquid that is inside of the electrode which helps replenish and create longer life. Electrodes take on the characteristics of the liquids they are measuring over time, that’s why a lot of complaints about meter is stuck on one reading.

Features:

  • Push-button calibration capabilities up to three points for a wide range of results
  • Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures
  • Transparent, protective cap keeps sensor moist when stored upright, and used as container for sensor conditioning or on-site calibration
  • Waterproof, dustproof housing is Ingress Protection (IP) 67-rated, for protection against solid objects or liquids
  • Large, upright, single-line LCD display screen for ease of viewing, and for display of indicators
