AquaMetrix P65R8-015 Differential pH Sensor with 4-20 mA Output: 1.45" Insertion Length

AquaMetrix P65R8 chemically resistant differential pH sensor offers a fixed insertion length for 1.5" NPT threaded flow-through or submersion installations, and an integral 4-20 mA output to connect with a PLC, DCS, or any process controller that accepts a 4-20 mA input.

The P65R8 has two pH measurement circuits - one for process measurement and one for internal reference - each containing a common titanium return electrode. The difference between the two circuits is the true process pH. With this design, the pH sensor maintains its accuracy and stability in aggressive process applications long after traditional combination-style sensor performance deteriorates.

The P65R5 features a built-in RTD in the sensor tip provides automatic temperature compensation, for rapid response in fluctuating process temperatures. Call Lesman to upgrade to a single sensor that outputs both pH and temperature at the same time.
