CPL57E Digital pH sensor Memosens

Field of application

The pH sensor Memosens CPL57E is specially designed for pure water applications in all type of industries. The glass sensor offers long-term stability, thanks to the additional salt storage, and ensures highly accurate measured values in pure water.

Memosens CPL57E is suited for:​

• Check of on-line measuring loops

• Analysis of grab samples (on-site as well as in the laboratory)

• Measurement at process points where regular checks are recommended​

In the following applications: ​

• Boiler feed water​

• Pure water​

• Water with low ionic strength

Benefits

• High accuracy and long-term stability of the pH electrode in pure water thanks to the additional salt storage

• Maintenance free sensor since the electrolyte does not need to be refilled

• Supports the requirements of quality management with tamper-proof data storage including serial number and calibration history

• Automatic temperature compensation thanks to an integrated temperature sensor
