The E+H Memosens CPS41E Digital pH Sensor features a liquid KCl electrolyte and a ceramic junction, making it extremely suitable for harsh chemical applications, fast-changing media, and liquids with low conductivity or high organic content. Extended storage of calibration and process allows for more accurate trend identification and expanded predictive maintenance, with secure digital transfer of historical data. Continuous refilling of KCl bridge electrolyte and a separate reference lead protect the unit from electrode ion poisoning. The non-contact, inductive signal transmission method of the CPF41E ensures maximum process safety.

E+H Memosens CPS41E Digital pH Sensor applications:

  • Chemical industry
  • Organic chemicals
  • Power stations
  • Laboratory measurements
