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.

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.

The conductivity of a liquid can be measured using the conductive or toroidal measuring principles. This video shows what it is about and how these measuring principles work.

Nutrients, metals or carbon components in a liquid can be measured using the colorimetric measuring principle. This video shows what it is about and how this measuring principle works.

This video shows how the unique design and sealing principle of the Cleanfit CPA875 retractable assembly guarantees safe sensor handling and prevents contamination of hygienic processes.
