  • Measurement and monitoring of the electrical conductivity of liquor samples
    Patent number: 4227151
    Abstract: A measuring cell for use in measuring and monitoring the electrical conductivity of a liquid. The cell comprises at least four concentric circular electrodes which are disposed in a flat or substantially flat surface. The concentric electrodes are mutually separated by annular areas of electrically non-conductive material.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.
