What the UT122's True RMS Measurement Actually Covers
True RMS matters most on non-sinusoidal AC signals — motor drives, dimmer-controlled loads, and anything downstream of a variable-frequency drive — where a cheaper averaging multimeter reads incorrectly. On the UT122, that True RMS accuracy applies across its full AC voltage range (6.000V/60.00V/600.0V), so readings on distorted AC waveforms stay reliable, not just on clean 50/60Hz mains.
Rechargeable Battery and Temperature Measurement
Two features separate the UT122 from the rest of the UT121 series:
- Type-C rechargeable battery. Instead of swapping AAA batteries, the UT122 charges over USB Type-C — one less accessory to keep track of.
- Temperature probe input. The UT122 measures from –40°C to 1000°C (±3°C), letting it double as a basic contact thermometer for HVAC, appliance, or automotive checks, alongside its electrical measurements. (A temperature probe is included as a standard accessory per UNI-T's official specification.)
UT122 vs UT121B: Which UNI-T Pocket Multimeter Fits?
The UT121 series covers three models, and the UT122 sits at the top of the range.
- Choose the UT122 if you want the highest capacitance range (99.99mF vs 60mF), a temperature probe, and Type-C rechargeable power in one unit.
- Consider the UT121B if you need the higher 750V AC / 1000V DC voltage range instead, and don't need temperature measurement or rechargeable power.
- Consider a higher-precision bench-style meter such as the UT61E+ (22,000 counts) if your work needs more display resolution than a 6199-count pocket meter provides.
Who Is This Multimeter For?
- Home and hobby users. Auto-range and dual display keep it simple for anyone who isn't a full-time technician.
- Electronics students. True RMS, temperature measurement and a slim 19mm body make it a practical all-in-one meter for a lab bag as the school term starts.
- Field and light maintenance work. A rechargeable battery removes one more thing to run out of on a job.
Frequently Asked Questions
Is the UT122 a True RMS multimeter?
Yes. True RMS measurement is listed as a standard feature, meaning AC voltage readings stay accurate even on non-sinusoidal or distorted waveforms, not just clean mains power.
Does the UT122 measure temperature?
Yes — it measures from –40°C to 1000°C (±3°C) using a temperature probe, which UNI-T lists as a standard included accessory for this model.
How is the UT122 charged?
It has a built-in rechargeable lithium battery charged over Type-C USB, unlike the UT121A/UT121B models in the same series, which use replaceable AAA batteries.
What's the difference between the UT122 and the UT121B?
The UT121B measures higher voltages (750V AC / 1000V DC vs the UT122's 600V) and uses AAA batteries, while the UT122 adds a higher capacitance range, a temperature probe, and Type-C rechargeable power instead.
What size and weight is the UT122?
Per UNI-T's official specification, it measures 144×71×15.5mm and weighs 157g.
Does it come with test leads?
Yes — UNI-T's standard accessories for the UT122 are batteries (built-in rechargeable), test leads, a temperature probe, and an English user manual.
Whether you're stocking a student lab bag or a home toolbox, the UT122 packs True RMS accuracy, temperature measurement and Type-C rechargeable power into a slim, pocket-sized body.
