Whether you troubleshoot and maintain electrical distribution, HVAC, or rotating equipment you probably use a digital multimeter (DMM) to test electrical parameters. If your company has an infrared camera (also called a thermal imager) you may have to go back to the shop to borrow it so you can quickly identify temperature differences that can point to problems. With a “thermal multimeter” you can do both with one tool that’s about the size of a DMM.
The Fluke 279 FC Thermal Multimeter is a professional DMM with an integrated infrared camera (also called a thermal imager). It works for just about any electrical application where you need to quickly locate a problem and then test standard electrical parameters.
To use it, simply turn the dial to the “IR camera” setting and scan the potential problem area. When you find a hot or cold spot, save the image, and note the location. Then turn the dial to the DMM function for the test you want to run, connect your test leads, and go to work. Remember to follow all appropriate safety guidelines and wear the appropriate PPE for the environment before testing in a live electrical environment.
Here’s what you get with a thermal multimeter:
