UT270 Series Clamp Earth Ground Testers

UT270 series can measure the grounding system of circuits without disconnecting the ground wires and auxiliary electrode. They clamp the grounding circuit and measure the grounding resistance fast and safely. They can measure resistance as low as 0.01Ω and have high resolution of 0.001Ω. They have overload alarm function, which can help to setup the alarm value within the ranges. The clamps have double insulation, which strengthens the anti-interference.
