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 2.0 glass sensor for the food & beverage industry and for bioreactors in biotech industry

Keep the pH value in the optimum range and maximize your product yield with Memosens CPS61E. Its rugged design and long-term stability ensure extremely accurate and reproducible measured values even after CIP/SIP or autoclaving. CPS61E features Memosens 2.0 digital technology, offering extended storage of calibration and process data for predictive maintenance. The sensor resists moisture and enables lab calibration, enhancing process integrity and increasing process uptime.
