UT139S True RMS Digital Multimeter
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.
1. True RMS
2. NCV
3. Auto/manual ranges selectable
4. 31-segment analog bar graph
5. Diode, duty ratio and continuity buzzer
6. Black EBTN screen
