Major Tech K4106 Earth Resistance and Resistivity Tester
The K4106 is a 2/3/4-wire Digital Earth resistance/Earth Resistivity Tester equipped with a microcomputer and can measure earth resistance and calculate earth resistivity (ρ), using the “Wenner” 4 pole method. This instrument is ideal for Earth measurements also in large Earthing systems because it uses a considerable test current of 80mA(max) yielding a high resolution of 1mΩ on 2Ω range. The Earth Resistivity measurement is useful for soil surveys to establish the optimum earth electrode system design and site, to avoid the extra cost of reworking electrode installations. It can also be suitable for geological investigations.
