CAT III 600V
Delivered between Fri, 13.6. and Tue, 24.6.

Product details

The UNI-T UT139S True RMS Digital Multimeter is a versatile measuring instrument for electricians. It can measure voltage, current, resistance, capacitance, frequency, and temperature. It features a True RMS function for accurate measurements of non-linear signals. Additionally, it has a NCV function that can effectively check the electrical status by measuring the EM field intensity. A special feature of the UT139S is the LoZ function (ACV), which is used to measure "ghost voltages." The device also has a built-in 31-segment analog bar display that provides a better visual representation of the measurement results. The UT139S has a black EBTN display and is ideal for working in dark environments. The device is CAT III 600V rated and comes with batteries, test leads, and a temperature probe.
