Product overview: Fluke 279 FC True-rms Thermal Multimeter
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.

Reviews: Fluke 279 FC True-rms Thermal Multimeter
Rated 5 out of 5 by Trickie Dickie from Much Better than expected This is a truly awesome instrument. Little skeptical about the built-in IR temp display. Turns out, it is super clear and surprisingly handy and has temp readout. Comes with a handy current loop which is a real step up from current clamps. Exceeded my expectations, but then again Fluke products always do.

Rated 5 out of 5 by Big Dave from Better Than Expeted After comparing the specs on the Fluke 279 and Flir DM284 I bought the Flir because the image quality was 2X better. After receiving the Flir I was disapointed with the image quality. I bought the Fluke. After getting it i compared the image quality of both side by side and the Fluke kills the Flir. The Flir's picture is grainy and not sharp. It has a lot of noise. The Fluke is clear, little noise and if you didn't know ou would think the Fluke had 2X the resolution. The Flir does have some nice MM functions but the Fluke has all you need. Also the Flir has a battery that you need to unscrew 4 bolts to change the battery.

Rated 5 out of 5 by WireBiter43 from Great meter! The IR feature saves time! The features on this meter are great. The best part is the IR feature. It saves a lot of time during the work day by preventing trips back to the shop to get the stand-alone IR camera. Fluke has got a great product! Just need to convince my boss to buy several more!

Rated 5 out of 5 by TeraMachines from The Best Tool In My Bag I religiously take this item with me to work because it is such a life saver. It will also save room in your back because you are combining many different tools. It is a bit pricey, but worth the money!! You will not regret this purchase!! I work in data centers and this thing saves me time daily because i can quickly see my hot spots and check voltages to problem areas.

Rated 5 out of 5 by Kevo from Best investment we've made in a while. Thermal imaging with the I Flex clamp.......what more do I need to say?
Oh yes, its compatible with Fluke Connect. First time we used it we found 2 loose lugs.

Rated 5 out of 5 by Saurus2 from It's a great investment I bought this with high expectations. And it hasn't let me down.
It is quick and very versatile.
I use it to find hot spots in the electrical panels and overheating bearings in electric motors. With the amp hoop it's a great tool.
