Fluke 561
HVACPro Thermometer
The Fluke 561 combines the temperature
measurement functions that industrial,
electrical, and HVAC/R professionals
need, all in one tool. It measures both
IR 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, you can
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, K-type mini-connector
thermocouple probe you already own.
