Endress + Hauser CPS31 analog pH sensor for application in potable water and swimming pools

ENDRESS + HAUSER analog pH sensor CPS31

Analog pH sensor 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.
Shaft length 120 mm, with or w/o temperature sensor

CPS31 measured value

  • pH
  • Temperature

CPS31 application

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

CPS31 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

CPS31 measuring range

pH: 1 to 12
Temperature: 0 to 80 ˚C (32 to 176 ˚F)

CPS31 process temperature

0 to 80 °C (32 to 176 °F)

CPS31 process pressure

1 to 4 bar (15 to 60 psi))

CPS31 storage temperature

0 to 50 °C (32 to 120 °F)
