Extended Specs at a Glance
Process temperature:
–15 to 80 °C (5 to 176 °F)
Measurement range:
pH 1 to 13
Process pressure:
0.8 to 4 bar (11.6 to 58 psi) (absolute)
Field of application
The Memosens CPS31E is a sensor for pH compensation in disinfection processes. It ensures safe drinking water and swimming pools by delivering stable measurement inputs. The sensor shows minimum drift thanks to a very low level of ion depletion in electrolyte.
Features
- Many options available: for minimum conductivities, 3 junctions are the best choice.
- Memosens offers maximum process safety thanks to non-contact, inductive signal transmission
