UNI-T UT281A Flexible Digital Clamp Meter

Description

Uni-T UT281A Flexible Digital Clamp Meter The UNI-T UT281A Flexible Digital Clamp Meter is a professional True RMS AC current measuring instrument featuring a flexible Rogowski coil that enables accurate current measurement around large cables, busbars, and crowded electrical panels. Unlike conventional clamp meters, its lightweight flexible sensor easily wraps around conductors with limited access, making it ideal for industrial power systems and maintenance applications. Designed for electricians and industrial technicians, the UT281A offers True RMS measurement, inrush current capture, data hold, backlit LCD display, and automatic power-off. Its rugged IP54-rated housing and 2-meter drop resistance provide reliable operation in demanding work environments, while the CAT IV 600V safety rating ensures dependable performance during electrical inspections. Features: 2m drop proof, ETL/Intertek certified 3rd edition CE. Coil diameter: 0.75cm, bending length: 45.7cm. Large LCD display for clear reading. True RMS. Long press INRUSH key for 2s to measure inrush current. Data hold, backlight, auto power off.
