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.

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 conductive conductivity sensor for standard applications in pure and ultrapure water

Condumax CLS15D is the digital solution for conductivity measurement in the low measuring ranges. It performs reliably and accurately in a wide range of applications - even in hazardous areas. Designed for low maintenance and a long operating life, the sensor offers best value for money. Condumax CLS15D is not the latest Memosens generation.
