Digital multimeter UT122

To select in the UT122 series, base your choice on your use and the voltages you measure. UT121A covers AC/DC measurements up to 600 V, UT121B goes up to 750 V AC and 1000 V DC with additional capabilities, and UT122 offers AC/DC measurements up to 600 V, resistance up to 60 MΩ, and capacitance up to around 99 mF. It also includes a rechargeable Li‑ion battery with USB‑C charging, a large 19 mm display, a 6000-count meter, and NCV/LIVE protection. Choose based on your safety and portability needs.

Automatic function identification quickly detects whether you’re testing voltage, current, resistance, or capacitance, which speeds up measurements without tedious manual setup. True RMS technology ensures accurate readings for non-sinusoidal signals—useful when working with real-world loads. In the UT122 range, this helps deliver reliable, fast results on both home and professional installations while still staying portable thanks to the built-in battery and USB‑C charger.

Professionals and technicians will appreciate the accuracy, NCV/LIVE protection, and stability even in mechanically demanding environments. Hobbyists and amateurs benefit from automatic function identification for measurements without hesitation, as well as an easy-to-read large screen. Versatility is strengthened by measurement ranges up to 600 V, resistance up to 60 MΩ, and capacitance close to 99 mF, covering most home applications and small industrial installations.

Recharge the device regularly via the USB‑C port to keep it ready to use. Store it in a dry place away from shocks, and wipe the connectors with a dry cloth if needed. Make sure the display and NCV/LIVE protection remain functional after each use. Avoid exposing the unit to moisture or extreme temperatures, and use it according to the intended operating conditions to preserve accuracy and instrument longevity.

The range covers essential measurements: AC/DC voltage (up to 600 V on UT122), resistance (up to 60 MΩ), and capacitance (up to about 99 mF on UT122). UT121A and UT121B add specific ranges or capabilities, including higher values and advanced measurements on some models. To compare quickly, first check the voltage range and resistance/capacitance values, then verify key features like automatic function identification, True RMS, and whether there’s a rechargeable battery.

If your priority is portability and versatile use on home installations, the UT122 provides a great balance with a rechargeable battery and clear display. For more demanding tasks or professional use requiring higher safety range coverage and more robust measurements, it may make sense to consider models that include stronger protections and higher measurement ranges. In any case, consider ease of use (automatic identification), reading reliability (True RMS), and the runtime offered by the built-in battery.
