There are hundreds of pH and ORP (redox) sensors in the marketplace. Only a few use differential technology. And only one is the legendary Aquametrix sensor. For three decades Aquametrix differential sensors 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.

Sensors are identified as either a pH (“P”) or ORP (“R”). There are two families of differential sensor: The 60 and 65 Series. The 60 Series output raw signal and connect with the 2250, 2251 and 2250 TX controller and transmitter respectively. The 65 Series sensor provides direct 4-20 mA output to a PLC or the Aquametrix 2300 controller.
