UNI-T UNI-T UT139C Multimeter

A True-RMS multimeter designed for professionals. It can easily be read in the dark since the 6000 count display has backligh... moreting. This meter is protected against drops and accidental bumps by a thick rubber casing. The multimeter can be used for AC and DC voltages and currents. On top of this it can also be used to measure capacitance, resistance temperature and frequency. Lastly, there is an NCV function which allows the meter to work as a wireless voltage locator. The UT139C multimeter comes with batteries, test leads, and a temperature probe.

UNI Multimeter UT139CDiscover the ultimate in measurement precision and professional-grade functionality with the UNI Multime... moreter UT139C. Engineered for electricians, HVAC technicians, and maintenance engineers, this robust digital multimeter delivers reliable and accurate readings in a wide range of demanding electrical environments. Its ergonomic design and advanced feature set make it the go-to instrument for complex troubleshooting and routine diagnostics.Achieve unparalleled accuracy on non-sinusoidal AC waveforms, such as those found in modern inverters and variable speed drives, thanks to its advanced True RMS measurement capability. This ensures you get trustworthy voltage and current readings every time, eliminating the guesswork associated with less sophisticated testers. Enhance your safety and efficiency with the integrated Non-Contact Voltage (NCV) detection, which allows you to quickly identify the presence of live voltage without making metallic contact, indicated by both audible and visual alarms. Confidently troubleshoot modern motor and inverter systems using the specialized VFC (Variable Frequency Drive) measurement mode, which applies a low-pass filter for stable and precise readings on noisy outputs. The large, 6000-count LCD display with a bright backlight guarantees effortless readability, even in poorly lit conditions.Main Features* True RMS Measurement for AC Voltage and Current* Non-Contact Voltage (NCV) Detection with Sensory Indication* Variable Frequency Drive (VFD/VFC) Measurement Mode* Full-Range Overload Protection* Auto and Manual Ranging Capabilities* Data Hold Function to Freeze Display Readings* MAX/MIN/REL (Relative) Measurement Modes* Capacitance, Frequency, and Duty Cycle Measurement* Temperature Measurement Function* Diode and Continuity Test with Audible Buzzer* Auto Power Off to Conserve Battery Life* Low Battery IndicationAttribute: TestersTechnical Specifications* Safety Rating: CAT III 600V* Display Count: 6000* DC Voltage: 600mV / 6V / 60V / 600V* AC Voltage: 6V / 60V / 600V* DC Current: 600μA / 6000μA / 60mA / 600mA / 6A / 10A* AC Current: 600μA / 6000μA / 60mA / 600mA / 6A / 10A* Resistance: 600Ω / 6kΩ / 60kΩ / 600kΩ / 6MΩ / 60MΩ* Capacitance: 9.999nF / 99.99nF / 999.9nF / 9.999μF / 99.99μF / 999.9μF / 9.999mF / 99.99mF* Frequency: 9.999Hz ~ 9.999MHz* Temperature: -40°C ~ 1000°C / -40°F ~ 1832°FWhether you are performing installations, conducting preventative maintenance, or diagnosing complex electronic failures, the UNI Multimeter UT139C provides the performance, safety, and advanced features required to get the job done right.

Model overview based on user reviews  
The UNI-T UT139A is a digital multimeter that offers a range of measurement capabilities, including voltage, current, and resistance, with both AC and DC options. It features True RMS capability, autoranging, and functions like diode and continuity tests. The device is equipped with a backlit display and a stand for ease of use. While it is generally considered a reliable tool, some users have noted that the beeper is slow and the hidden wiring detector is not very effective. Additionally, it may take a while to measure large capacitances. Despite these drawbacks, it is appreciated for its accuracy and ability to connect current clamps up to 60A. However, for those specifically interested in measuring capacitance, alternatives like the MCL500 might be more suitable. Overall, the UNI-T UT139A is a solid choice for standard multimeter functions, but may not be the best option for specialized capacitance measurements.
Pros

Cons

Overall, a cool tester.

If you take it for the sake of measuring capacitance, it’s better to take the MCL500, it is priced like another multimeter, but it measures super (capacitance and inductance)! And the rest of the usual multimeter.
Accurately displays; features TRUE RMS capability, can connect current clamps (up to 60A).
Slow beeper, does not measure below 100n, takes a long time to measure large capacitances.
normal model, nothing special

Not worth your money!

The squeaker sticks. hidden wiring detector works poorly beeps everywhere is practically useless.
