Knick pH Measurement
For measuring pH values in process applications, we offer numerous designs, e.g. also glas and glas-free ISFET sensors. The digital pH measurement is carried out using the Memosens technology, which enables preventive diagnostics for sensor health.
Our sensors are available with explosion protection, different sensor lengths and a wide range of connection possibilities. They are suitable for a large selection of Knick fittings, such as SensoGate and Ceramat as well as inline, flow-through and immersion fittings.
