Product overview: Fluke i2500-18 iFlex® Flexible Current Probes

Be Ready for Anything

The Fluke iFlex® flexible current probes expand the measurement range of the select Fluke meters to 2500 A AC while providing the ultimate measurement flexibility. The iFlex® probes connect directly to the meter, displaying current measurements without error prone scaling factors. The 1.8 m (6 ft) cord allows separation between the measurement location and the clamp meter making it easier to view the display. The large loop size and thin cross section allow measurement of awkward sized conductors and improved wire access in crowded spaces. Available in 25 cm (10 in) and 45 cm (18 in) sizes.
