Classic Ground Resistance Tester Using 3-Pole Method with Easy Cord Winding System
Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The FT3151 Analog Earth Tester uses the AC phase differential system to measure earthing resistance, which assures that accurate measurements are unaffected by earth voltage and auxiliary earthing resistance. New innovate cord winders make clean up a breeze.
