Abstract

1330295 Measuring conductivity PLESSEY CO Ltd 7 Dec 1970 [12 Nov 1969] 55485/69 Heading G1N In a conductivity cell C of the kind comprising two current electrodes 1, 4 supplied with a direct current i and two voltage electrodes 2, 3 spaced apart between the current electrodes, a further current electrode 5 is provided to prevent current flow externally of the cell. The cell may be used to measure salinity.
