Product Overview
The Fluke i2500-18 iFlex® Flexible Current Probe is designed to enhance the versatility of compatible Fluke clamp meters by extending their AC current measurement capability up to 2500 amperes. Unlike traditional clamp jaws, the flexible Rogowski coil allows you to measure large conductors, bus bars, and cables in confined or hard-to-reach spaces with ease.
The thin 7.5 mm coil provides improved wire access in crowded panels, while the 1.8-meter cable enables safe and comfortable viewing of the meter display away from live conductors. With direct meter connection, readings are displayed accurately without error-prone scaling calculations.
Available in 45 cm (18 in) loop size, the i2500-18 is ideal for industrial maintenance, electrical troubleshooting, power distribution, and high-current applications.
