UNI-T Digital Clamp Meter UT201+ - True RMS HVAC Multimeter

In this review of the UNI-T UT201+ clamp meter the bottom line is simple: this is a practical, safety-minded clamp multimeter for technicians who need reliable AC current readings and basic system diagnostics. The reviewer found the unit best suited to HVAC, automotive and general electrical troubleshooting thanks to its True RMS measurement, NCV detection and a 28 mm jaw that handles most conductor sizes. It is an auto-ranging, easy to use tool with a large LCD and solid build, making it a worthwhile daily driver for tradespeople and advanced DIYers.

Key Features

• True RMS & auto ranging: Delivers accurate AC readings on non-sinusoidal loads so technicians can trust current and voltage measurements across real equipment.
• 400 A AC capacity: The clamp measures up to 400 A AC, making it suitable for most HVAC and industrial circuits without needing direct connections.
• Multifunction tests: Measures AC/DC voltage to 600 V, resistance, capacitance, frequency and offers continuity and diode testing for broad troubleshooting.
• NCV detection: Built-in non-contact voltage warning speeds up live-circuit checks and reduces the time spent hunting for energized conductors.
• Safety rated: CAT III 300 V and CAT II 600 V ratings plus fuse protections on ranges help protect the user and the meter on typical jobsite circuits.
• Portable design: A 28 mm jaw, nonslip rubber grip, carrying case and 4,000 count display make it easy to carry and read on the worksite.

Who It's For

The UT201+ is aimed at HVAC technicians, electricians and automotive technicians who need a compact clamp meter for frequent AC current checks, system frequency and voltage diagnostics. Its True RMS capability is particularly useful where variable-speed drives or non-linear loads are present.

It is also a good choice for serious DIYers who work on household electrical systems and appliances. However, those who need advanced features like temperature probes, inrush current measurement or higher clamp capacity should consider other models in the UNI-T line or dedicated instruments.

Pros & Cons

Pros

• True RMS and auto-ranging for reliable readings on real-world electrical loads.
• Compact clamp with 28 mm jaw and NCV makes live testing fast and convenient.
• Broad function set including AC/DC voltage to 600 V, frequency, capacitance and continuity.
• Clear, large digit LCD and nonslip grip improve usability on the job.

Cons

• Does not include temperature or dedicated inrush current measurement found on some higher-end models.
• Jaw opening is limited to 28 mm, so very large conductors may require a different meter.
