Digital Clamp-On Ground Earth Resistance Tester Ground Resistance Meter 0.01-1000 Ohm 99 Sets 0.001 Leakage Current ,Easy to Use

In the measurement of a grounding system with loop, does not require breaking down the grounding wire, and need no auxiliary electrode. It is safe, fast and simple. Clamp on ground resistance tester is equipped with a long jaw sized 55mmX 32mm, particularly suitable for the grounding with the flat steel. Can measure the integrated value of the earthing body resistance and lead resistance of grounding 55 * 32mm jaw size for larger ground rods Measurements of resistance to ground Autoranging of 0.01Ohm to 1000Ohm with resolution of 0.01Ohm
