Abstract

This invention relates to an electrical measuring probe for determining the electrical conductivity of a liquid comprising a measuring zone extending longitudinally through the probe, through which the liquid to be measured flows and to which an electrical current is applied between electrodes, the electrodes having electrical leads remote from the liquid to be measured and those parts of the electrodes remote from the liquid to be measured forming a mechanically stabilizing and electrically conductive insertion or conductor frame of an electrically insulating sleeve which determines the shape of the probe. The insertion frame contains individual conductors in the sleeve distributed axially symmetrically in relation to the longitudinal axis of the probe, and the sleeve is made by injection-molding and consists of a chemically stable thermoplastic.
