Field of application

Ceratex CPS31 is the analog expert for pH compensation in disinfection processes. Its three diaphragms make it suitable for minimum conductivity while its low drift guarantees stable measurement. The sensor makes sure that swimming pool water is agreeable and drinking water tasteful.

  • Drinking water

  • Swimming pool water

  • pH compensation for free chlorine measurement

Benefits

  • Reliable measurement at minimum conductivity thanks to three diaphragms

  • Low drift by very low level of ion depletion in electrolyte

  • Optional salt ring for extended operating time

Videos

  • 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.
