Non-contact fluid conductivity sensor

The sensor allows non-contact measurement of the electrical conductivity of liquids.

To determine the conductivity of a liquid, a unique technology of non-contact conductivity measurement is used, which excludes contact of the measuring electrodes with the liquid.
The flow of electrolytic processes on the surface of the measuring electrodes, which are always accompanied by the release of electrolysis products and contamination of the liquid, is excluded.

Contacts are located in the same plane.
Measures the temperature of a liquid.

The sensor is available in flat and cylindrical versions as shown in the pictures below.
