Conductivity Inductive

Optical sensor for inductive conductivity.
The inductive conductivity sensor has 2 toroidal coils which are housed in a plastic casing and therefore do not come into contact with the surrounding solution. For this reason, it is physically impossible for the sensor surface to become soiled, coated or contaminated.

Since the inductive conductivity sensor does not determine the conductivity via electrodes, but via electrical fields, no polarization effects occur. Thus the sensor provides more accurate measurement results, especially for measurement media with high conductivities.

The sensor housing is made of Noryl, which is extremely resistant to chemicals.
