UT278A Clamp on Ground Resistance Tester Leakage Current Tester
UT278A is a 1200Ω auto range clamp earth ground tester of resistance and 30A leakage current with 1s single measuring time and current limit alarm. UT270 series 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.
