Fluke 378 FC Non-Contact Voltage True RMS AC/DC Clamp Meter with iFlex®

The Fluke 378 FC Non-Contact Voltage True RMS AC/DC Clamp Meter with iFlex® is a premium industrial clamp meter engineered for electricians, maintenance technicians, HVAC professionals, and industrial service teams who need safer, faster, and more advanced electrical diagnostics. Featuring innovative FieldSense™ technology, the 378 FC allows users to measure voltage and current through the clamp jaw without direct metallic contact to a live conductor, significantly improving safety while simplifying troubleshooting in high-energy environments.

The Fluke 378 FC combines True RMS accuracy, wireless Fluke Connect® compatibility, advanced power quality indication, and high-current flexibility into one rugged handheld platform. The included iFlex® flexible current probe extends AC current measurement capability up to 2500A while allowing access around large conductors, bus bars, and crowded electrical cabinets. The meter also performs complete three-phase voltage and current tests in just three steps, automatically calculating phase-to-phase values and phase rotation through the Fluke Connect ecosystem.

Unlike traditional clamp meters, the 378 FC includes an integrated Power Quality (PQ) indicator that automatically identifies whether electrical problems originate from upstream power supply issues or downstream equipment faults. This allows technicians to quickly diagnose voltage instability, power factor problems, and harmonic-related issues without requiring a dedicated power quality analyzer.
