UNI-T UT278B & C & D Series Ground pile clamp earth resistance tester:
The UNI-T UT278B, UT278C, and UT278D Series Ground Pile Clamp Earth Resistance Testers are specialized instruments designed for measuring earth resistance in grounding systems. These testers feature a robust clamp design that allows for non-invasive measurements, making them ideal for testing ground resistance without the need for disconnection.
UT278B/C/D Series grounding clamp meters are used for the grounding resistance test. With clamp measurement, 3-wire or 4-wire measurement, voltage/current measurement, data storage/view, alarm, automatic shutdown, and other functions.
Models: UT278B, UT278C, UT278D
