Abstract

A cell for the measurement of the dielectric properties of liquids, pastes or flowable solids (i.e. solids whose melting temperatures are low enough to allow them to be poured into the cell) comprises a bullet-shaped internal electrode having its cylindrical portion in register with a surrounding coaxial cylindrical external electrode which is extended at each end by electrically conductive annular guard members insulated from the external electrode by means of spacers of electrically insulating material. The internal electrode is mounted coaxially within the external electrode by means of a tapered male-female centering connector whose male and female elements are both connected to earth.
