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.

Memosens contactless sensor coupling
SE554 pH Sensor | Memosens | 120 mm
Ex | For very high ionic strength media
Low-maintenance sensor for demanding process application in the chemical industry, digital, with Memosens technology
- 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
- Open junctions, no blocking
- Alpha glass, medium impedance, universal glass, fluoride resistant
High accuracy, stability, rapidness, and a long life cycle are achieved by the special design. Through 2 open junctions, the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction. The high content and special distribution of potassium chloride in the polymer reduces measurement disturbances which could be caused by liquid junction potentials.
Applications
Industrial applications, dyes, precipitation reactions, polluted media
