Abstract

A sensor for use in measuring and monitoring the electrical conductivity of a liquid comprises at least four concentric circular electrodes (10, 12, 14, 16) which are disposed in a surface (30) which is preferably flat. The concentric electrodes are mutually separated by annular areas (11, 13, 15) of electrically non-conductive material. Electrode 10 may incorporate a temperature compensation thermistor. Also disclosed are a system for monitoring the electrical conductivity of a liquor sample and a system for comparing the electrical conductivities of two liquor samples both of which systems include a measuring cell having the aforegoing construction. <IMAGE>
