Analog non-glass pH sensor
Tophit CPS441

ISFET electrode for the chemical, life sciences and food industries

  • Tophit CPS441 - Analog non-glass pH sensor with refillable liquid KCl electrolyte ©Endress+Hauser
  • The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

Tophit CPS441 is the analog high performer for media with low conductivity or a high content of organic solvents. Designed for fast response, it accurately measures even in fast-changing medium compositions. Its unbreakable shaft ensures absolute safety of your products.


  • Unbreakable for highest product safety

  • Resistant to poisoning thanks to constant refilling of KCl bridge electrolyte and separate reference lead

  • Suitable for sterilization

  • Low maintenance thanks to long calibration intervals

적용 분야

Media with a high amount of organic solvents or very low conductivities:

  • Chemical industry including precipitation reactions or dispersions (pressurized version)

  • Power plants, e.g. boiler feed water

  • Life sciences, e.g. water for injection

With 3A, ATEX, FM and CSA approval suitable for hygienic applications or hazardous areas.
