Uni-T UT139S True RMS Digital Multimeter
$1,399.99
UT139S is CAT III 600V digital multimeter designed for electricians. Its NCV feature can effectively check the electrical status by measuring EM field intensity. The new UT139S 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 a black EBTN display and is a perfect meter for working in dark environments.
