The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

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 ISFET electrode for the chemical, life sciences and food industries

Tophit CPS441D is the digital high performer for media with low conductivity or high organic solvents content. Designed for fast response, it accurately measures even in fast-changing medium compositions. Its unbreakable shaft ensures best safety of your products. Thanks to Memosens digital technology, CPS441D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
