UNI-T UT258A AC/DC Leakage Current Clamp Meter – 0–60A, 1mA Resolution, 7mm Jaw, 10000-Count, RS-232, Zero Adjustment
The UNI-T UT258A is a precision AC/DC leakage current clamp meter built for measuring small leakage and load currents down to the milliamp — essential for insulation fault-finding, RCD/earth-leakage diagnosis and equipment safety testing. Its narrow φ7 mm jaw and 10000-count display resolve currents from 0 mA up to 60 A.
A zero-adjustment function removes residual magnetism for stable low-current readings, and the RS-232 interface with 99-group storage lets you log results to a PC. Genuine UNI-T product supplied by Digilog.pk with warranty — a specialist tool for electrical maintenance, panel and safety-compliance work.
