AEMC Clamp-On Ground Resistance Tester

Clamp-On Ground Resistance Tester

The AEMC 6418 clamp-on ground resistance tester, with auto calibrating oblong jaws and large OLED display, verifies the quality of the grounding connections and bonds. It measures ground rods, bus bars, grid resistance and impedance without auxiliary rods. It operates in a multi-grounded system without disconnecting it, differentiates between loop and ground resistance, and offers two alarms for amps and ohms.
