Lighten up your toolbox. The Fluke 561 IR and contact thermometer, combines the temperature measurement functions that industrial, electrical, and HVAC/R professionals need, all in one tool. It measures both infrared and contact temperature, replacing several other test tools. It’s fast, efficient, and easy to use, saving you valuable time and effort.

With the Fluke 561 infrared thermometer, you can also take contact and ambient temperatures in the way that’s best for you. Use the IR thermometer to measure hot, moving, electrically energized, and hard-to-reach objects instantly. Check motors, insulation, breakers, radiant heating, pipes, corroded connections, and wires. Plus, scan ducts, and other hard-to-reach objects from the floor-leave your ladder in the truck. You can use the Fluke 561’s handy flexible pipe probe, or plug in any industry standard type K mini connector thermocouple probe you already own to take super-heat or internal temperatures.
