Knick 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.
Knick 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.

SE515 pH Sensor | Memosens | 120 mm
Sigma glass | For water and wastewater treatment
Reasonably priced sensor for water and wastewater treatment
- Perfect galvanic isolation thanks to Memosens technology
- No influence of humidity in the connector
- Precalibration in the lab
- Digital data transfer
- Integrated sensor diagnostics
- Low maintenance, no refilling of electrolyte
- Integrated temperature detector
- Ground-glass sleeve junction
- Sigma glass; low impedance for low-temperature applications
Thanks to its ground-glass sleeve junction even applicable in heavily contaminated media. Designed for MemoRail applications. High stability and a long life cycle are achieved by the special design.
Through a ground-glass sleeve junction the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction.
Measurement is possible even at low temperatures thanks to a special low-impedance glass.
