UT270+ series can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need for 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 from the environment.
