Product Overview

The Fluke 368 FC Leakage Current Clamp Meter is a specialized true-RMS leakage current measurement tool designed to detect, document, and trend very small leakage currents without shutting down equipment. It is ideal for identifying insulation deterioration, grounding issues, and intermittent RCD/GFCI trips before they escalate into costly downtime or safety hazards.

Equipped with a fully shielded jaw for high accuracy at very low current levels and Fluke Connect® wireless connectivity, the Fluke 368 FC enables technicians to track leakage current trends over time using a smartphone or tablet. With 1 μA resolution, a 40 mm jaw, and a rugged industrial design, it is perfectly suited for preventive and predictive maintenance in industrial, commercial, and critical power environments.

Key Features

• True-RMS Leakage Current Measurement – Accurate results on complex, non-sinusoidal waveforms
