About Earth Resistance Testers

Every electrical system must be assessed to ensure earthing is correctly implemented. By using earth resistance testers, the user can evaluate the overall resistivity of earth underfoot and gain comprehensive knowledge of earth resistance.

To test, four wires (four-wire terminal method) are used in combination with earthing spikes to determine a value of earth resistance. By doing this, it is possible to determine the overall effectiveness of ground grids and connections used with electrical systems for protection and is also an excellent way to propsect for low resistance grounding locations by using the values gained to determine what's underneath the earth's surface (such as depth to bed rock).

At PASS, we stock a selection of earth resistance tester from the most popular manufacturers including Fluke, Kewtech, Martindale, Metrel and UNI-T.
