The UNI-T UT139S is a CAT III 600V True RMS digital multimeter designed for professional electrical work. It features NCV capability for checking electrical status through electromagnetic field intensity. The device is equipped with a black EBTN display, which provides high contrast and clear readability in dark environments.

The multimeter includes specialized functions such as LoZ (ACV) for measuring ghost voltage and a 31-segment analog bar for a more traditional visual representation of measurement results. It offers full protection up to 600 V and supports both automatic and manual range selection. Functional modes include MAX/MIN/REL, data hold, and a LED backlight. The unit is powered by two 1.5V batteries and includes an automatic power-off feature to conserve energy.
