Abstract
1368713 Electro-physical measurement - moisture J JACKSON 18 July 1973 [19 July 1972] 33816/72 Heading G1N In a soil moisture meter of the type using a probe which generates its own operating potential, both electrodes are tapered to ensure good contact with the soil as it enters. As shown a conical zinc tip 1 forms the anode which is separated by insulation 2 from a hollow brass cathode 3 which is joined directly to a tubular metal stem 4. The stem is preferably of a smaller diameter than the top of the electrode so that the electrode contact area is reasonably well defined. The stem may be coated with insulation.
