Two-in-one infrared and contact

thermometer for HVAC/R Professionals

The multipurpose thermometer you need
for HVAC jobs.

Lighten up your toolbox. The Fluke 561 HVACPro
combines the temperature measurement functions that
professionals need for most HVAC jobs, all in one tool. It
measures both IR and contact temperature, replacing
several hundred dollars worth of equipment. 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 from the floor—leave
your ladder in the truck. You can use the Fluke 561’s
handy Velcro
tool investments, plug in any industry-standard K-type
mini-connector thermocouple probes you already own.

heat and sub-cooling and

other contact and ambient

measurements

• Single-point laser sighting

• Temperature range optimized

for HVAC/R applications

• Easy emissivity adjustment

for measuring pipes and ducts

more accurately

• Lightweight (just 12 ounces/

340 grams) and portable

• Very easy to use

• Efficient—no need to shut down

equipment when making IR
measurements

• MIN, MAX and DIF functions

help you quickly identify
problems

• Scan large areas or small

objects quickly and efficiently

Laser-guided sighting for
IR measurements

When using the Fluke 561 in
the IR mode, the single dot, laser
sighting system guides measure­ments to the right target. The dot
indicates the approximate center
of the measurement area.

When measuring smaller objects, use the Fluke 561 within 6 ft. (1.75 m)
of the intended target. The measured area increases with distance
(the distance divided by 12, approximately).
