    Product overview: Fluke 279 FC True-rms Thermal Multimeter

    Find, repair, validate, and report electrical issues quickly

     

    Locate the problem immediately

    Thermal imaging multimeters are a first-line troubleshooting tool for electrical equipment that can check hot spots on high-voltage equipment and transformers, and detect heating of fuses, wires, insulators, connectors, splices, and switches. Scanning with the 279 FC's thermal imager reveals many electrical issues rapidly and from a safe distance. By combining two tools into one, the thermal multimeter lightens the load and increases productivity.

    Expanded functionality

    Compatible with iFlex® (a flexible current clamp) to expand your measurement capabilities and get into tight, hard-to-reach spaces for current measurement (up to 2500 A AC). The large full-color LCD screen makes for easier and clearer viewing of images and readings. The 10-hour+ rechargeable battery keeps you going all day long under normal conditions.

    With built-in Fluke Connect®, transmit results wirelessly to a smartphone and save time on reporting to validate work is complete. Troubleshoot better by instantly trending and monitoring measurements live on your smartphone screen. Create and email reports right from the field.
