AEMC 3731 Clamp-On Ground Resistance Tester

The AEMC 3731 Clamp-On Ground Resistance Tester measures ground rod and small grid resistance in any environment without the use of auxiliary ground rods. The AEMC 3731 can be used in multi-grounded systems without disconnecting the ground under test. It simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
