The UNI-T UT278B is a handheld ground pile clamp tester that centers on simplicity and reliability for on-site earth resistance checks. Its most notable design element is the large, 2.4-inch color display, which presents measurements clearly and makes menu navigation intuitive, even in direct sunlight or low-light conditions. The unit’s molded housing incorporates a hinged, 68 mm-wide jaw that opens easily to encircle grounding rods or conductors without requiring disconnection streamlining routine inspections. Internally, the UT278B combines a rechargeable lithium-ion battery pack with real-time power monitoring, so users can trust it will remain powered through long field sessions; recharging is achieved via a standard USB socket when convenient.
Onboard electronics employ fast-filtering algorithms to isolate actual ground resistance readings from stray noise, ensuring that displayed values are stable within one second of measurement. Stored data can be transferred seamlessly to a PC via USB, allowing for straightforward record-keeping and trend analysis. At under 1 kg, the tester balances weight and ruggedness: its reinforced insulation and over-voltage protection safeguard both the operator and the instrument in demanding environments.
Overall, the UT278B presents a refined blend of ergonomic handling and modern display technology to expedite earth resistance diagnostics without added complexity.
