Product Overview

The Fluke 378 FC Non-Contact Voltage True-RMS AC/DC Clamp Meter with iFlex is an advanced, safety-focused electrical measurement tool designed for fast and reliable troubleshooting of modern electrical systems. Featuring FieldSense™ technology, the 378 FC enables technicians to measure voltage, current, and frequency without making direct contact with live conductors, significantly reducing risk and speeding up diagnostics.

Engineered for industrial electricians, maintenance engineers, and facility professionals, the 378 FC supports single-phase and three-phase measurements, includes a power quality indicator, and connects wirelessly to Fluke Connect™ for data logging and reporting. The included iFlex® flexible current probe allows accurate current measurement up to 2500 A in crowded panels and large conductors.
