UNI-T UT278C Series Ground Pile Clamp Earth Resistance Tester
The UNI-T UT278C is a portable clamp-style instrument designed to simplify earth resistance testing on grounding rods, ground grids, and similar installations without needing to disconnect conductors. Encased in a rugged, double-insulated housing, the unit features a hinged jaw that opens to 68 mm, easily clamping around grounding electrodes or parallel conductors. Once clamped, the UT278C injects a small test current and measures the resulting voltage drop to calculate ground resistance, displaying results on a bright 2.4-inch color LCD.
The large screen presents readings clearly and enables intuitive menu navigation, even in bright sunlight or dimly lit environments. Internally, the UT278C’s electronics employ fast-filtering algorithms to minimize interference from nearby live cables, ensuring stable values within one second of measurement. A rechargeable lithium battery pack powers the unit, with real-time battery status shown on-screen; recharging is accomplished via a standard USB port when convenient. The instrument can store up to 500 test records, which can later be uploaded to a PC via USB for reporting and analysis.
Weighing just under 1 kg, the tester balances durability and portability: its reinforced insulation and built-in overload protection safeguard both operator and device in harsh field conditions. In practice, the UT278C provides technicians with a fast, non-intrusive way to verify grounding integrity without additional auxiliary rods or circuit interruptions.
