Fluke 369 FC Leakage Current Clamp Meter

Product Overview

The Fluke 369 FC Leakage Current Clamp Meter is a high-performance true-RMS leakage current clamp engineered for professionals who need to detect, trend, and document extremely small leakage currents on large conductors—without taking equipment offline. Featuring a large 61 mm fully shielded jaw, it accurately captures microamp-level leakage while minimizing external electromagnetic interference.

With built-in Fluke Connect® wireless connectivity, the 369 FC lets technicians trend leakage current over time on a smartphone or tablet, helping identify insulation degradation, grounding issues, and intermittent RCD/GFCI trips before they cause unplanned downtime. Its rugged design, LED worklight, and backlit display make it ideal for dark panels and demanding industrial environments.

Key Features
