Condumax CLS21D ©Endress+Hauser

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 medium to high measuring ranges

Condumax CLS21D is a robust conductivity sensor for all process and environmental applications. It provides you with precise and reliable measuring values for an optimum process and product quality monitoring. Better still, the sensor features high chemical, thermal and mechanical stability and high durability. Thanks to Memosens digital technology, CLS21D combines maximum process and data integrity with simple operation. It resists corrosion and moisture and facilitates predictive maintenance.
