The UNI‑T UT521 is a reliable earth ground resistance tester designed for fast, accurate grounding checks in homes, offices, factories, and field sites across Pakistan. It measures earth resistance using 2‑pole/3‑pole methods and displays earth voltage, helping you verify grounding quality and detect unsafe conditions before they become problems. A clear LCD, data hold, and simple keys make testing straightforward—even for first‑time users.
With ranges typically up to 2000 Ω and earth voltage up to 200 V AC, UT521 covers most earthing jobs for generators, solar arrays, distribution panels, and lightning protection systems. The instrument’s stable test current and self‑fusing measurement method deliver repeatable results, while auto power‑off extends battery life. Rugged construction, protective sleeve, and a soft carry case (model dependent) keep the kit field‑ready. Supplied test leads and auxiliary earth spikes make setup quick on site.
