Uni-T UT139C is a versatile digital multimeter for more demanding work in electrical installations and maintenance. It offers True RMS for more accurate measurement of AC signals, NCV for quick non-contact voltage checking, a safety rating of CAT III 600 V, and a clear display with a bar-type analog graph.
True RMS and wide measurement capabilities

True RMS and wide measurement capabilities

Measures AC/DC voltage up to 600 V and AC/DC current up to 10 A, as well as resistance, capacitance, frequency, and temperature. Thanks to True RMS, you get more accurate results even for non-linear AC waveforms.

NCV and CAT III 600 V safety

NCV and CAT III 600 V safety

The NCV function enables quick non-contact checking for the presence of voltage. The design and protections comply with CAT III 600 V for work in switchboards and installations.

Practical operation and readable display

Practical operation and readable display

A large LCD is complemented by a 31-segment bar graph for quick monitoring of changes. Data Hold, Max/Min, and backlight are included for work in poorer lighting conditions.

The Uni-T UT139C digital multimeter is the best-equipped model in its series—ideal wherever you need wide ranges, good readability, and functions for everyday diagnostics. Thanks to True RMS mode, it provides more reliable results when measuring AC voltage and current, while the V.F.C. function helps when working with signals with variable frequency.

The multimeter measures voltage up to 600 V and current up to 10 A, and also includes resistance, capacitance, frequency, and temperature measurement (probe included). A clear LCD is complemented by a 31-segment bar graph for quick evaluation of value changes.

Main advantages and features:

  • NCV – non-contact voltage detection for quick installation checks
  • Automatic and manual range selection for convenient measurement
  • Diode test and audible continuity test
  • Data Hold, relative mode, and Max/Min
  • LCD backlight and auto power-off
  • CAT III 600 V safety rating
