Field of application
Memosens CPS31E is the expert for pH compensation in disinfection processes. It delivers stable measurement results, ensuring safe swimming pool and drinking water. Thanks to Memosens 2.0 digital technology, CPS31E provides the perfect data basis for predictive maintenance, offers easy operation and more process uptime since it can be calibrated in the laboratory and quickly exchanged on site. The sensor resists moisture and its 3 optional junctions make it suitable for minimum conductivity.

Swimming pool water
pH compensation for free chlorine and free bromine measurement
Benefits
Reliable: Ceramic junction ensures reliable measurement at low conductivities. For minimum conductivities, 3 junctions are the best choice.
Robust: The optional salt storage provides for extended operating time.
Precise: The sensor shows minimum drift thanks to a very low level of ion depletion in electrolyte.
Memosens 2.0 offers extended storage of calibration and process data. These data are the ideal basis for predictive maintenance and can also be used to develop and provide enhanced IIoT services.
Safe: Non-contact, inductive, digital signal transmission eliminates errors due to moisture.
Cost-efficient: Fast sensor exchange in the field increases process uptime and regeneration extends the sensor lifetime.
