FLUKE-377FC True-RMS AC/DC Clamp Meter with iFlex

The Fluke 377 FC offers a safer, faster way to measure voltage and current using FieldSense™ technology—without contact with live conductors. Ideal for industrial electricians and maintenance professionals, this meter allows complete 3-phase voltage and current tests in just three steps, displaying results on the meter or syncing them wirelessly to the cloud via Fluke Connect®.

Equipped with an iFlex® flexible current probe, the 377 FC measures up to 2500 A AC and provides easier access around large conductors in confined spaces. Visual Continuity enhances usability in noisy areas, while the large backlit display and automatic range selection ensure clarity and convenience on the job. The rugged design make it a reliable tool for any demanding environment.
