Earth Resistance & Soil Resistivity Testers

KUSAM-MECO Digital Earth Resistance Tester is a very versatile& handy instrument for checking Earth Resistance. It consists of the indicator & set of 3 spikes (stake) and connecting wires. Earth Resistance is measured by putting the spikes in the earth at distance of 5-10m (as shown below) & switching ON the instrument indicates the Earth Resistance directly in ohms.
