UT139 Series True RMS Digital Multimeters
UT139 series UT139 is a CAT III 600V digital multimeter for electricians. Its NCV function can effectively check the electrical condition by measuring the EM field intensity. The new UT139E/S models have special functions such as LoZ (ACV) for measuring "ghost" voltage. The built-in 31-segment analog scale also allows electricians to better visualize the measurement results. The UT139S is designed with a black EBTN display, making it a great meter for working in dark environments.
UT139 series models: UT139A, UT139B, UT139C, UT139S
