UT276A/UT278A Clamp Earth Ground Testers (Discontinued)
UT276A/UT278A Clamp Earth Ground Testers (Discontinued)
UT276A/UT278A 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. These clamps’ double insulation design makes them durable tools for outdoor work and effective in blocking interference signals from the environment.
