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. 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.Rugged construction, protective sleeve, and a soft carry case (model dependent) keep the kit field‑ready.
