Water-treatment professionals choose SEKO's electrical conductivity probes for their precision, reliability and repeatable results.

Conductivity represents one of the fundamental parameters in determining the quality of water and liquids in general because it is linked to the concentration of ions responsible for electrical conduction in a solution.

Electrical conductivity is the reciprocal of electrical resistivity and measures the ability of a solution to conduct an electric current when an alternating voltage is applied to a measuring cell made up of two or four electrodes.

To compensate for the geometry of the cell, each probe is characterized by a constant that can be expressed in two ways which are the inverse of one another and are indicated with the letters K and C, the first expressed in cm and the second in cm-1.

The conductivity of a solution is generally expressed in μS/cm.
