Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.

Memosens 2.0 ORP sensor for applications with fast-changing medium compositions or low conductivity

Memosens CPS42E is the high performer for harsh chemical applications, media with low conductivity or considerable organic content. The sensor is designed for fast response especially in applications with fast-changing media. Thanks to Memosens 2.0 digital technology, CPS42E combines maximum process integrity with simple operation. It resists moisture and enables lab calibration. It offers extended storage of calibration and process data providing the perfect basis for predictive maintenance.
