UNI-T UT281E True RMS Flex Clamp Meter – Flexible AC Current Tester

The UNI-T UT281E is a professional-grade flexible clamp meter designed for HVAC technicians and electricians who frequently work in cramped electrical panels and industrial environments. Featuring a flexible Rogowski coil, this tester allows you to measure AC current in spaces where traditional rigid jaw clamps simply cannot reach, such as thick cable bundles and oversized busbars.

Equipped with True RMS technology, the UT281E ensures high-precision readings even on distorted waveforms often found in modern commercial buildings. With a measurement capacity of up to 3000A AC and a rugged build, it is the ultimate tool for heavy-duty electrical maintenance and troubleshooting.

Why It Matters

In the field, accessibility is often the biggest challenge. A standard clamp meter can be impossible to use inside a crowded switchboard or around large-diameter conduits. The UT281E solves this problem with its 18-inch flexible coil, providing the maneuverability needed to maintain safety and accuracy in high-voltage industrial and commercial settings without the frustration of limited space.

Technical Specifications

Tradie Pro Tip

When measuring in a tight panel, try to position the flexible coil so the conductor is as close to the center of the loop as possible. This minimizes magnetic field interference and ensures you get the most accurate True RMS reading every time.
