A conductivity system is only as good as the sensor or cell which provides the signal to the analyzer or controller. Water Analytics Inc., with many years of experience in the measurement of conductivity, manufactures a wide variety of conductivity cells to satisfy any industrial, power plant or laboratory application. In addition to the standard line, all types are available for high temperature applications.

The AS and AM series probes all work with the Shark controller, Shark-TX transmitter and most other manufacturers’ analyzers. The ES-5 toroidal sensor provides a direct 4-20 mA output that can straight to the 2300 controller. The ES-1 is meant to work with Hach or Knick controllers.

There are hundreds of pH and ORP (redox) probes in the marketplace. Only a few use differential technology. And only one is the legendary Aquametrix probe. For three decades the Aquametrix differential probes have set the standard for durability, longevity and precision. These sensors may cost more up front but, in very aggressive processes, they will end up saving money over the years.

Every model comes as either a pH (“P”) probe or ORP (“R”) probe. All but one class of sensors are meant to be used with the Shark controller or Shark TX transmitter. The P/R-65 series of differential probes provide direct 4-20 mA output for a PLC or the AquaMetrix 2300 controller.

For applications that involve clean water and that do not need years of service from a probe a combination probe is an economic alternative. These probes are sometimes called for when the process is so aggressive that no probe lasts longer than a year. The 500 sereies probes come in a fixed insertion or a variable insertion form factor. They can be ordered with automatic temperature compensation or a pre-amp to allow transmission over distances greater than 10 feet. Models are also available that contain an HF resistant antimony electrode and a hardened glass electrode.

Controllers & Transmitters

AquaMetrix has been making controllers and transmitters for over three decades. The 2200 controllers for pH, ORP, conductivity and flow put the AquaMetrix name on the map due to their ruggedness and simplicity. The Shark controller and Shark TX transmitter replaced all four 2200 models with one multi-parameter, single-input analyzer. After 10 years of a stellar track record the Shark and Shark TX have been replaced by the AM-2250 and AM-2250TX. With greater measurement accuracy and features that you actually need these two new models will set a new standard for durability and ease of use for the next decade.

The AM-2300 multi-parameter, multi-input controller is the first and only web-enabled analyzer that brings SCADA functionality to a small package that anyone can configure and use. One day all controllers will work like it.
