UT139 series are CAT III 600V digital multimeters 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.
