pH Sensors

For measuring pH values in process applications, we offer different sensor versions, including glass and glass-free ISFET sensors. The digital pH measurement is performed using Memosens technology, which enables a preventative diagnostics buffer of the sensor condition.

Our analog and digital pH sensors are available with explosion protection, in different sensor lengths, and with various connection options. They are suitable for a wide range of fittings, including SensoGate and Ceramat retractable fittings as well as inline, flow-through, and immersion fittings.
