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 glass electrode for standard applications

Orbisint CPS11D is the digital all-rounder for process and environmental technology. It measures reliably even in highly alkaline media or hazardous areas. Designed for low maintenance and a long operating life, the electrode offers you best value for money. Thanks to Memosens digital technology, CPS11D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
