Introduction
The Fluke 67 MAX Infrared Thermometer (the Product) can determine the surface
temperature by measuring the amount of infrared energy radiated by the subject’s skin.
WWarning
Read all safety information before you use the Product.
It is important to understand there are inherent differences in accuracy between skin-surface
temperature measurements obtained with an IR thermometer versus subdermal/core
temperature measurements made with a contact thermometer.
ASTM laboratory accuracy requirements in the display range of 37 °C to 39 °C (98 °F to
102 °F) for IR thermometers is ±0.3 °C (±0.5 °F), whereas for mercury-in-glass and electronic
thermometers, the requirement per ASTM Standards E667-86 and E1112-86 is ±0.1 °C
(±0.2 °F).
Proper measurement technique is critical to keep sources of error to a minimum. Potential
error sources include measurement distance to subject, measurement location, anatomical

variations between subjects, ambient temperature conditions, failure to observe the
maximum-displayed reading, and more.
A correction between skin temperature at the forehead and sublingual (under the tongue)
temperature was determined by a clinical study of adult subjects. The Product has not been
tested on children and thus, is subject to error when used on children under 18 years of age.
Characteristics and procedures are available from the manufacturer upon request. The
Product defaults to body mode that incorporates this correction into the displayed
measurement to compensate for this effect.

WWarning
To prevent personal injury or possible misdiagnosis of body temperature:
•Read all safety information before you use the Product.
•Do not alter the Product and use only as specified, or the protection
supplied by the Product and its measurement accuracy can be
compromised.
•Before you use the Product, inspect the case and optical lens. Look for
cracks in case plastics, scratches, or other damage to the optical lens.
Do not use the Product if it appears damaged.
•Do not use in ambient environments outside of the specified operating
temperature and humidity range or subject the Product to excessive
mechanical shock. Permanent damage to the Product including
inaccurate temperature measurement may result.
•Do not use or store the Product in direct sunlight or near other sources
of radiant heat. This can cause the Product temperature to differ from
ambient conditions and affect measurement accuracy. Allow the Product
time to equalize to ambient conditions before use.
•Do not use the Product around explosive gas, vapor, or in damp or wet
environments.
•Do not use the Product if it operates incorrectly.

•Optical lens components must be free of moisture, dust, and debris to
ensure measurement accuracy. Clean and disinfect only as specified.
•Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.
•Do not store the Product for long periods with the battery installed to
prevent battery leakage.
•Repair the Product before use if the battery leaks. Battery leakage may
damage the Product.
•Do not attempt to service the Product.

Note
When ambient conditions change significantly, wait 30 minutes for the Product to
stabilize before you use it or the accuracy may be impacted. For example, if the
Product is brought from cold or hot outdoor conditions into a building.
Aim the Product for Body Temperature
When you use the Product to measure body temperature, make sure that the Product shows
the correct temperature. When you measure the subject’s temperature, make sure the skin of
the forehead is unobstructed by hair, eye glasses, or anything that could interfere with the
emitted infrared energy. Make sure the distance to subject is 50 mm to 150 mm (2 in to 6 in),
or accuracy may be impacted. Make sure the Product is in Body mode. See Figure 1.
