Conductivity measuring principal

Conductivity measuring principal

Conductive probes feature two electrodes that are positioned opposite from each other. An alternating voltage is applied to the electrodes which generates a current in the medium. The intensity of the current depends on the number of the medium's free anions and cations that move between the two electrodes. The more free anions and cations the liquid contains, the higher the electrical conductivity and the current flow. The conductivity unit is "Siemens per meter".
