Aprašymas

Uni-T UT139B True RMS Digital Multimeter The Uni-T UT139B is a True RMS digital multimeter designed for everyday electrical measurements, combining user-friendly operation with greater reading accuracy. The device operates in CAT III 600V category, offers an NCV function for quickly checking the condition of an installation, and features an easy-to-read display supported by a 31-segment analog bar graph. It is a mid-range model in the series that provides a good balance between functionality and precision. Greater precision and ease of measurement The UT139B 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. Compared to the UT139A model, it offers a higher maximum reading of 4000, while retaining the V.F.C. function and automatic and manual range switching. This makes it better suited for applications requiring greater precision and more convenient result monitoring. Features for enhanced user comfort The UT139B is equipped with a diode test, continuity buzzer, duty cycle measurement, Data Hold function, Relative mode, Max/Min function, and LCD backlight. The UT139 series also provides full protection up to 600 V, automatic shut-off, and True RMS measurement. It is a practical choice for users who want a more advanced multimeter for service and electrical work.
