The Fluke 62 Mini

Infrared Thermometer

For quick, basic temperature checks

Advances in technology have

made the smallest infrared ther-

mometers, such as the Fluke 62

Mini, especially practical. They’re

convenient to carry and afford-

able enough for everyone on an

entire crew to own one, so that

infrared temperature measure-

ment isn’t limited to specialists.

And the latest models are more

accurate and measure greater

temperature ranges than earlier

“mini” generations.

Point, shoot and read

To use the Fluke 62 Mini Infrared

Thermometer, use the laser sight-

ing to pinpoint the target, and

pull the trigger to see the tem-

perature on the built-in display.

Increases in temperature are

often the ﬁrst sign of trouble for

mechanical equipment, electri-

cal circuits and building systems

such as heating, ventilation and

air conditioning (HVAC). A quick

temperature check of key compo-

nents and equipment can detect

potential problems and prevent

catastrophic failures. Regular

contact measurement with a

thermometer and probe takes

time and can require getting

close to dangerous or inaccessible

operational equipment or shutting

equipment down. Non-contact

infrared (IR) thermometers take

quick, safe measurements from

a distance while equipment is

operational.

Check motor temperatures quickly, without contact.

The thermometer works by

measuring the infrared energy

emitted from surfaces and con-

verting the information into a

temperature reading. It measures

temperatures from -30 °C to

+500 °C (-20 °F to +932 °F), is

accurate to ± 1 % of reading and

can capture the maximum reading

among a range of readings.

While there are endless ways

to use an infrared thermometer,

here are the three primary ones:

1) Measure the absolute

temperature at a spot. This

is useful for trending the

temperature of an object such

as a bearing housing over

time. With a repeatability of

± 0.5 %, the new thermom-

eters make this practice quite

accurate.

2) Compare the temperature

differential of two spots. For

example to compare the run-

ning temperatures of two like

objects to determine if one is

overheating.

3) Scan an object and detect

changes within a continuous

area on it, to ﬁnd hot or cold

spots on housings, panels and

structures.

Securing accurate

measurements

The uses for handheld infrared

thermometers are limited only by

the nature of infrared technology.

The key restriction is the sur-

face of the target object. Simply

stated, these instruments cannot

accurately measure shiny sur-

faces. The issue is emitted versus

reﬂected energy.

Popular applications Even considering the limitations of infrared temperature monitoring, there are still so many possible uses for this technology that trying to list them all would be fruitless. Here are some of the most common and particularly successful applications. Predictive maintenance Regular maintenance in industrial and institutional locations keeps motors, pumps and gearboxes from experiencing catastrophic failures that can halt production or pose safety problems.
