UNI-T UT281C Digital Flex Clamp Meter – Flexible, Reliable, and Built for High Current Measurement

The UNI-T UT281C Digital Flex Clamp Meter is a professional-grade instrument designed for measuring large AC currents safely and accurately. Equipped with a flexible Rogowski coil, this clamp meter can measure currents up to 3000A AC, making it ideal for industrial maintenance, electrical installation, and power system monitoring.

Whether you’re working on thick cables, irregularly shaped conductors, or in tight spaces, the UT281C delivers accurate and efficient current readings every time.

Flexible Rogowski Coil for Easy Measurement

The UT281C features a 450mm flexible coil sensor that can easily wrap around large conductors, bus bars, or multiple wires—perfect for environments where traditional clamp meters cannot fit.

This flexible coil design provides non-contact current measurement, ensuring maximum safety and ease of use without the need to disconnect power lines.

True RMS for Accurate Readings

Thanks to True RMS (Root Mean Square) technology, the UT281C ensures precise measurement of both pure and distorted waveforms, such as those generated by inverters, variable frequency drives (VFDs), and switching power supplies.

It provides AC current measurements from 0.1A up to 3000A, covering a wide range of professional applications in power systems and electrical engineering.

Bright Backlit Display and User-Friendly Interface

The large LCD display with backlight ensures clear readings even in poorly lit environments. With intuitive buttons for Data Hold, MAX/MIN recording, and Zero Adjustment, the UT281C allows users to quickly capture and review measurements without errors.

It’s lightweight, ergonomic, and designed for one-handed operation — making it a practical choice for on-site work.

Safety and Durability

The UNI-T UT281C meets CAT IV 600V / CAT III 1000V safety standards, ensuring protection against transient voltages in high-energy electrical environments.

Its rugged housing is made from impact-resistant materials, providing long-lasting durability in industrial conditions. The non-contact measurement design reduces risks when measuring high current conductors.
