UNI-T UT208B 1000A AC/DC True RMS Digital Clamp Meter
The UNI-T UT208B is a rugged, auto-ranging 1000A AC/DC True RMS clamp meter built for fast, safe and accurate electrical diagnostics. With a clear 6000-count display, analog bar graph and a full set of advanced functions, it handles everything from motor and VFD troubleshooting to solar DC checks and HVAC servicing.
Why choose the UT208B?
- True RMS measurement – reliable readings on non-linear loads such as inverters, drives and power supplies.
- AC and DC current up to 1000A – ideal for industrial equipment, batteries and solar systems, not just AC circuits.
- Inrush current capture – records the start-up surge of motors and compressors.
- LoZ ACV mode – low-impedance voltage test that eliminates misleading “ghost” voltage.
- LPF ACV mode – low-pass filter for accurate voltage readings on inverters and variable frequency drives.
- NCV non-contact voltage detection – multi-segment display with audible and visual alarm.
- Temperature measurement – with K-type thermocouple, 0.1°C resolution, °C/°F selectable.
- Built-in flashlight & auto backlight – work comfortably in panels, ducts and dark spaces.
- Safety rated – CAT III 1000V / CAT IV 600V, CE/ETL certified.

Frequently asked questions
Can the UNI-T UT208B measure DC current?
Yes. Unlike entry-level clamp meters, the UT208B measures both AC and DC current up to 1000A.
What is True RMS and why does it matter?
True RMS meters give accurate readings on distorted waveforms from inverters, drives and electronic loads, where average-responding meters can read incorrectly.
Does it have non-contact voltage detection?
Yes. The NCV function at the clamp tip detects live AC voltage with a multi-segment display and an audible/visual alarm.
Can I measure temperature with it?
Yes. Connect the K-type thermocouple to measure temperature in °C or °F.
Is it safe for industrial use?
The meter is rated CAT III 1000V / CAT IV 600V and is CE/ETL certified. Always follow the safety instructions in the manual.
