Product Details
UNI-T UT281E+ Flexible Rogowski Coil Clamp Meter, 6000 Counts True RMS, 10000A AC Current, 6000A Inrush Current, 1100mm Coil, 1000V AC/DC, CAT III 1000V CAT IV 600V, IP54.
UT281E+ is a professional True RMS flexible Rogowski coil clamp meter built for heavy industrial high-current testing. It features a 6000-count display and a 1100mm long flexible coil, suitable for measuring large busbars, thick cables and crowded switchgear where rigid clamp meters cannot fit. It supports up to 10000A AC current and 6000A inrush current capture to check the startup surge of motors and transformers. It also measures AC/DC voltage up to 1000V, resistance up to 60MΩ and continuity test. Dual LCD screen shows readings and frequency simultaneously. It stores 999 sets of measurement data with data hold, review and delete functions. It meets CAT III 1000V / CAT IV 600V safety rating, IP54 dust & water resistance and 2m drop resistance. Ideal for power distribution, photovoltaic, metallurgy, rail and industrial maintenance technicians.
