Field of application
Memosens CPS47E is the high performer with liquid KCl reference for media with low conductivity or high organic load. It measures accurately even in applications with fast-changing media. Its unbreakable shaft ensures best product safety. Thanks to Memosens 2.0 digital technology, the pH sensor resists moisture and enables lab calibration, increasing process safety and simplifying operation. Its extended storage of calibration and process data provides a perfect basis for predictive maintenance.
Media with a high amount of organic solvents or very low conductivities:
Chemical industry, measurement of media prone to clogging
Power plants, e.g. boiler feed water
Life sciences, e.g. water for injection
With all relevant approvals for hygienic applications such as EHEDG, 3A, EU1935/2004, USP 87/88
Benefits
IIoT ready: Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
Unbreakable: Non-glass PEEK body ensures highest product safety where glass breakage is intolerable.
Resistant to poisoning: Constant refilling of KCl bridge electrolyte and separate reference lead prevent poisoning ions from entering the electrode.
The sensor is suitable for autoclaving and sterilization with hot steam offering long-term stable measurement.
Low maintenance: ISFET technology is insensitive to temperature changes enabling long calibration intervals
Maximum process safety: Thanks to non-contact, inductive signal transmission, problems with moisture are a thing of the past.
Reduced operating costs: Laboratory calibration and fast sensor exchange on-site minimize process downtime and extend sensor lifetime
