Fluke 561 Technical Data

Fluke 561 Infrared and
Contact Thermometer
IR thermometer with K-type
thermocouple capability
The multipurpose thermometer you need.
Lighten up your toolbox. The Fluke 561 combines the
temperature measurement functions that industrial, elec-
trical, 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.
Features include:
•
IR thermometer for quick mea-
surements up close, or at a
distance, without a ladder
•
Contact thermometry capability,
compatible with all standard
mini-connector K-type ther-
mocouples, preserves your
investment in thermocouples
•
Velcro pipe probe for super-
®
heat and sub-cooling and
other contact and ambient
measurements

•
Temperature range of -40 °C
to 550 °C (-40 °F to 1022 °F)
covers most industrial and
residential applications
•

Laser-guided sighting for
IR measurements
When using the Fluke 561 in
the IR mode, the single dot, laser
sighting system guides measure-
ments 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).
