Fluke 279 FC True-RMS Thermal Multimeter

The Fluke 279 FC is a groundbreaking tool that integrates a full-featured digital multimeter with a thermal imaging camera, making it easier to detect, validate, and troubleshoot electrical problems in one device. This dual-function capability allows technicians to spot hot spots and anomalies quickly and then verify issues with precision electrical measurements—all without switching tools.

With wireless connectivity via the Fluke Connect® app, technicians can save, analyze, and share measurements and images in real time, enhancing safety and productivity. The built-in infrared camera helps locate issues faster by identifying overheating components like fuses, motors, or connections. Designed for demanding environments, the 279 FC is rugged, reliable, and ideal for industrial, HVAC, and facility maintenance professionals.
