UT281E+ 10,000A Flexible AC Current Meter

The UT281E+ uses a flexible coil instead of a rigid jaw, so it wraps around large or awkward conductors — busbars, cable bundles, tight gear — to measure AC current up to 9.99 kA. It's rated CAT III 1000 V / CAT IV 600 V and True-RMS, with inrush-current capture for motor and transformer start-up.

A dual display shows two values at once, voltage and resistance round out the electrical set, and 999 result sets store on-board. The 1000 mm flexible coil and AA-battery power keep it practical for utility and industrial feeder work. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT281E+ Details

Flexible-Coil Current Measurement

A flexible coil wraps around conductors a rigid clamp can't reach — large busbars, cable bundles, and crowded switchgear — and measures AC current up to 9.99 kA, opening up high-current work in tight or oversized installations.

Inrush Capture & True-RMS

Inrush-current capture records the surge when motors and transformers start, and True-RMS sensing keeps AC accurate on distorted waveforms across the 10 Hz–1000 Hz measurement band.

Working Set & Storage

A dual display shows two readings at once, AC/DC voltage to 1000 V and resistance round out the electrical measurements, and 999 result sets store on-board for later review.

Applications

High-current feeder and busbar measurement; motor and transformer start-up (inrush) testing; utility and industrial maintenance on large or awkward conductors; and switchgear work where a flexible coil reaches what a clamp cannot.
