Differential Probes

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.
