Fluke 279FC I/B Wireless True RMS Thermal Multimeter with iFlex

Fluke 279FC I/B Wireless True-RMS Thermal Multimeter is designed for electricians and maintenance professionals who need to locate electrical problems quickly and safely. By combining a full-featured digital multimeter with integrated thermal imaging, it allows users to identify hot spots without direct contact—reducing risk and troubleshooting time.

With an 80 × 60 thermal sensor and a large 3.5-inch color display, the 279FC enables fast detection of overheating components such as fuses, wires, breakers, and transformers. The included iFlex flexible current probe extends current measurement capability up to 2500 A, making it ideal for tight or hard-to-reach conductors. Wireless Fluke Connect compatibility allows measurements and thermal images to be logged, shared, and trended from a mobile device.
