UNI-T UT251C+ — high-accuracy, high-sensitivity AC leakage current clamp meter built for tracing earth leakage down to 1 µA resolution and up to 60 A. The large 40 mm jaw clamps around cable bundles, while strong anti-interference design and a low-pass filter (LPF) hold the reading stable near noisy loads. Adds harmonic testing, dual display and Bluetooth logging — ideal for checking leakage on motors, home appliances and electrical equipment. Genuine UNI-T product supplied by Digilog.pk with user manual and warranty.
