Memosens CPS47D pH sensor with KCl liquid electrolyte filled reference, ceramic diaphragm and KCl refill nozzle

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 CPS47D – Digital non-glass pH sensor with refillable liquid KCl electrolyte

Memosens ISFET electrode for the chemical, life sciences and food industries

Memosens CPS47D is the digital high performer with liquid KCl reference for media with low conductivity or high organic solvents content. Designed for fast response, it measures accurately even in applications with fast-changing media. Its unbreakable shaft ensures best 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.
