UNI-T clamp/earth meter UT278A+, up to 1200Ω, 20A SKU: UT278APLUS

Description

UNI-T clamp/earth meter UT278A+, up to 1200Ω, 20A

The UT278A+ can quickly and safely measure system grounding without disconnecting circuit ground lines or the need for auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω. The double-insulated design of this clamp makes it a durable tool for outdoor work and effective at blocking environmental interference.
