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.

  • Memosens CPS77D – Digital ISFET sensor for food and life sciences industries

Memosens ISFET electrode for food and life sciences industries

Memosens CPS77D is the digital specialist for hygienic applications. Its bacteria-proof reference with contamination-resistant gel guarantees stable measurements. The sensor is sterilizable with hot steam, autoclavable and features an unbreakable PEEK shaft assuring highest product safety. In addition, the Memosens digital technology combines maximum process and data integrity with simple handling. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
