UNI-T UT139B True RMS Digital Multi-meter True RMS Meter Handheld Tester 6000 Count Voltmeter Temperature Tester Meters UT-139B

UT139 series are CAT III 600V digital multi-meters designed for electricians. Its NCV feature can effectively check electrical status through measuring EM field intensity. The new 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. UT139S is built with black EBTN display and it is a perfect meter for working in dark environments.
