UNI-T UT139S True RMS Digital Multimeter

The UT139S True RMS Digital Multimeter from UNI-T is a versatile measuring device for electricians. It can measure voltage, current, resistance, capacity, frequency, and temperature. It features a true RMS function for accurate measurements of nonlinear signals. It also 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) used for measuring "ghost voltages". The device also has an integrated 31-segment analog bar display, providing a better visual representation of the measurement results. The UT139S has a black EBTN display and is a perfect measuring tool for working in dark environments. The device is protected to CAT III 600V and it comes with batteries, test leads, and a temperature probe.
