Digital non-glass pH sensor Memosens CPS77D

Memosens CPS77D – Digital ISFET sensor for food and life sciences industries ©Endress+Hauser

Memosens CPS77D with improved CIP stability

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.
