Abstract
A cell for the measurement of electrical conductivity of liquids by the principle of the four electrode measuring technique in which two current electrodes are spaced from one another and voltage electrodes provide a voltage tap-off. The voltage electrodes include at least two voltage electrodes associated with each current electrode and electrically connected in parallel. The at least two voltage electrodes are disposed along an equipotential line around a current electrode at positions on the equipotential line which exhibit low current density.
