Clamp on ground earth resistance tester

The UYIGAO UA6412+ ground resistance clamp testers represent a new generation of earth/ground clamp-on resistance testers. These instruments induce a test current into earth systems and measure ground resistance in multi ground installations without needing to disconnect the ground.
