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

  • Memosens technology
    Memosens 2.0: Cutting-edge sensor technology reloaded

    Make life easier, increase process safety and stay connected with Memosens 2.0 digital technology.
