UNI-T UT275 Clamp Earth Ground Tester
UT275 can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need of auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω. UT275 can also measure leakage current up to 30A. These clamps’double insulation design makes them durable tools for outdoor work and effective in blocking interference signals from the environment.
