In comparing an unsymmetric stabilized cell for measuring the electrical conductivity based on a continuous capillary made of BeO with an inner ring-shaped cavity with symmetric unstabilized cells with large volumes of a temperature-stabilized material, the characteristic features of the axial and radial migration of impurities in the insulator envelopes at high temperatures and pressures are studied. The advantages of the proposed cells, associated with the reduced danger and probability of seal failure and contamination of the substance studied, determining the accuracy of the measurements, are pointed out. The results of measurements of the electrical conductivity of pure mercury in the allowed pressure and temperature ranges, obtained in the cells with improved insulating properties of the ceramic, are presented.
