UNI-T UT276A+ | Clamp Earth Ground Tester

The UNI-T UT276A+ Clamp Earth Ground Tester is designed for safe, fast measurement of grounding-system resistance without disconnecting the grounding conductor or installing auxiliary electrodes. It is part of UNI-T’s UT270+ clamp earth ground tester series, which measures resistance from 0.01Ω with 0.001Ω resolution, uses double insulation for outdoor durability, and includes auto range, data hold, data recall, LCD backlight, resistance limit alarm, low battery indication, auto calibration, jamming signal recognition, and over-range display.

Pro Tip

Use the supplied test ring before field measurement to confirm the tester is responding correctly; this reduces the risk of publishing or recording doubtful grounding data. Buy UNI-T UT276A+ from Kamadi Pakistan for clamp-type earth resistance testing and electrical safety maintenance.

Buyer’s Selection Guide

Choose the UT276A+ if your main requirement is clamp-type earth resistance testing with a 32mm jaw, EBTN display, and 300 data storage groups. For simultaneous earth resistance plus leakage current display, compare with UT278A+.
