UNI T UT139S True RMS Digital Multimeter Introduction

The UNI-T UT139 series are CAT III 600V digital multimeters designed for electricians. Its NCV feature can effectively check the electrical status by measuring EM field intensity. The UT139E/S models include special features such as LoZ (ACV) for measuring ‘ghost’ voltage. Its built-in 31-segment analog bar also gives electricians a better visual representation of measurement results. The UT139S is built with a black EBTN display and it is a perfect meter for working in dark environments.
