Endress + Hauser CPS31D digital pH sensor for application in drinking water and swimming pools

ENDRESS + HAUSER digital pH sensor CPS31D

Digital pH sensor CPS31D is the digital expert for pH compensation in disinfection processes. Its three diaphragms make it suitable for minimum conductivity while its low drift guarantees stable measurement.
Shaft with temperature sensor.

CPS31D measured value

  • pH
  • Temperature

CPS31D application

• Drinking water
• Swimming pool water
• pH compensation for free chlorine measurement

CPS31D advantages

• 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
• Maximum process safety through non-contact inductive signal transmission
• Enables predictive maintenance due to storage of sensor and process-specific data
• Reduced operating costs due to minimized process downtime and extended sensor lifetime
