Product Description

UT-139B is a universal digital meter used for measuring: voltage, current, resistance, capacitance, frequency and checking the correctness of diodes. The meter has a function of automatic change of measurement ranges, as well as a relative measurement mode. The device also has a built-in battery tester. For AC measurements, a filter has been built into the device to eliminate high-frequency interference that can affect measurement accuracy (VFC). In addition, it has an electric field detection function (NCV).
