Uni-T UT139A True RMS digital multimeter

The Uni-T UT139A is a True RMS digital multimeter designed for electricians who need a convenient and safe tool for everyday measurements. The device operates in CAT III 600V category, offers an NCV function for quick inspection of the installation, and features an easy-to-read display supported by a 31-segment analog bar graph. This model combines the series’ basic functionality with practical solutions that facilitate field work.

Basic measurements with additional features

The UT139A model allows for the measurement of DC and AC voltage up to 600 V, DC and AC current up to 10 A, resistance, capacitance, and frequency, and additionally offers 1.5 V and 9 V battery testing. It stands out from other models with a maximum reading of 2000 and the inclusion of the V.F.C. (low-pass filter) function. Automatic and manual range switching allows you to adapt the operation to a specific measurement and enhances user convenience.

Ease of use and safety

The UT139A is equipped with a diode test, continuity buzzer, duty cycle measurement, Data Hold function, Relative mode, and LCD backlight. The UT139 series also offers full protection up to 600 V, automatic shut-off, and a True RMS function that increases measurement accuracy. It is a practical solution for users looking for a reliable multimeter for standard electrical tasks.
