Ideal for measuring ground impedance on ground rods and bus bars, this ground resistance tester measures without auxiliary rods and is perfect for multi-grounded systems without disconnecting or de-energizing the ground system under test. In addition, this tester features EN 61010-1, 100 V CAT IV, and 150 V CAT III safety standards.

Quickly and easily clamp this ground resistance tester around the grounding electrode or conductor and measure the resistance to the ground. By performing measurements on intact ground systems, verify the quality of the grounding connections and bonds. Additionally, measure the resistance and continuity of grounding loops around pads and buildings.
