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.

Features

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

7. LPF (low pass filter) function

8. LoZ (low impedance input) function
