Description
The E+H Memosens CPS31E Digital pH Sensor is designed for drinking and swimming water treatment applications, with a gel-filled reference and ceramic junction suitable for accurate pH monitoring of medias of low conductivity. Minimum drift occurs in the sensor thanks to low ion depletion in the electrolyte. Salt storage comes optional with each unit for longer operating time. Extended storage of calibration and process allows for more accurate trend identification and expanded predictive maintenance, with secure digital transfer of historical data via Memosens 2.0 technology. The non-contact, inductive signal transmission method of the CPS31E ensures maximum process safety.
