A digital multimeter is a device that measures two or more electrical quantities, primarily voltage (volts), current (amps), and resistance (ohms) (ohms). For technicians in the electrical and electronic industries, it is a typical diagnostic tool.
Fluke 279 FC True-rms Thermal Multimeter helps you find, repair, validate, and report many electrical issues quickly so that you are confident problems are solved.
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.
Communicate your results
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.

Work Faster, Safer and Easier with CNX Wireless Test Tools
Fluke’s CNX Wireless Test Tools put tools, not your body, near live electrical panels. It’s simple. Connect the remote modules, whether they are voltage modules, current clamps, flexible current loops or thermometers, and read the results on the CNX 3000 Wireless Multimeter from a safe distance. You can display the meter measurement, plus readings from up to 3 wireless modules.
Don’t Get Bogged Down While Isolating Intermittent Electrical Faults
Timing is everything when trying to find an intermittent problem and the hard part is, it doesn’t always show up when you have your meter connected. We’ve solved that problem with CNX – leave your CNX remote modules connected to log measurements and walk away to address other issues. You can then download the data for further analysis.
Work Safely Near Electrical Panels While Wearing Less PPE
Personal protective equipment (PPE) can save your life, but it’s bulky, hot and hard to work in. With CNX, there’s no need to work in front of live open panels or moving/hazardous machinery.
Picture having the ability to access live readings without being exposed to the live panel. It’s easy. Just deenergize the cabinet, open the panel while wearing PPE and connect your CNX modules. Close the cabinet, reenergize and let the CNX multimeter work, reducing the risk of arc flash by separating yourself from hazardous measurement situations.
Testing 3-Phase is Now Faster and Cheaper
When your cabinet is deenergized, attach a CNX current clamp to each phase. Close, reenergize and start taking readings. What used to take hours and use costly equipment can be done in minutes with an affordable CNX wireless system.
Take 3-Phase Measurements in 1/3 the Time. Add your laptop and go from logging to analysis and diagnosis
You can solve problems faster by seeing live measurements from multiple test points on a single screen. With a CNX wireless test tool, you can:
Take 3-phase measurements in 1/3 the time
Add your laptop and go from logging to analysis and diagnosis
Record over time using the CNX wireless modules and monitor circuit load changes for an hour, a shift or a week
Use the CNX wireless USB adapter to collect logged data from remote modules by walking past a working module and downloading logged data
Perform for analysis with your PC and the CNX wireless test tool software. View data or graphs to see problems easily on the computer display
