Lighten up your toolbox with the one tool that combines the temperature measurement functions that professionals need most for inspecting heating, ventilation, air conditioning and refrigeration systems.
The Fluke 561 HVACPro Infrared Thermometer provides both non-contact and contact temperature measurements, replacing several other test tools. It is fast, efficient and easy to use, saving you valuable time and effort.
The Fluke 561 infrared thermometer comes with K-type thermocouple capability, so 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 Velcro® pipe probe, or plug in any industry standard type K mini connector thermocouple probe you already own to take super-heat or internal temperatures.
