UNI-T UT139B True RMS Digital Multimeter Details
Test AC/DC voltage and current, resistance, capacitance, frequency, continuity, diode and more with this digital multimeter!
The upgraded version of the UNI-T UT139A, the UT319B includes extra functions compared to the other model such as capacitance and frequency testing. All measurements are performed with a high degree of accuracy and the meter is also true RMS to ensure accurate results when testing on irregular waveforms.
The meter also includes a number of additional functions such as a built-in non-contact voltage detector, auto and manual ranging options, auto power off when left idle, data hold, MAX/MIN, a relative mode and more.
This digital multimeter is CAT III 600V rated.
