Earth Ground Tester - 

MP760838 is a clamp earth ground resistance tester, used for testing grounding resistance. This device can quickly and safely measure the grounding system without disconnecting circuit ground lines or the needs of auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω, and can also measure leakage up to 20A. The device features an EBTN display type of which displays current and resistance simultaneously, and features data storage (300 sets), data access, data upload, alarm and automatic shutdown. The device is controlled by a microprocessor and can accurately detect the ground resistance, it uses a fast filtering technique to minimize interference. The double insulation design of this clamp meter makes it durable for outside work and effective in blocking interference from the environment. With a shockproof, dustproof and moisture-proof structure, the tester is commonly used for telecommunications, electricity, meteorology, oil fields, electromechanical installation and maintenance.
