The electrical conductivity of an organic liquid is an important parameter, e.g., for assessing electrostatic charging in industrial processes with regard to flammability or explosion of the fluid. In oils, for example, the measured value provides information about aging effects that have an influence on lubricity or wear protection. For liquid dispersions, electrical conductivity provides information about the colloid chemical conditions of the dispersed particles in the medium.
Creepage current measurement is suitable for measuring electrical conductivity in non-aqueous organic liquids or dispersions.
In the method implemented in the DT-700, an alternating voltage is applied to the liquid or dispersion between two coaxial stainless-steel electrodes using a cylindrical measuring probe. The current is measured and the electrical conductivity is determined.
