Measuring Liquid Temperatures
To accurately measure the temperature of
liquids and semi-liquids, such as soup, chili,
salad dressing, etc., stir the liquid to bring the
internal temperature to the surface, while
taking a measurement with the unit in noncon-
tact mode. Steam, dust, smoke, etc., can pre-
vent accurate measurement by interfering with
the energy emitted from the target. To increase
the reliability of the measurement, do not hold
the unit directly over a steaming or smoking
product. Instead, hold the unit back and at
an angle to ensure the most accurate
measurement

Measuring Packaged Products
in Cold Storage Cases
Ideally, the temperature of a product should
be measured outside of a refrigerated environ-
ment whenever possible. If it is necessary to
measure the product in a refrigerated environ-
ment such as a walk-in cooler, either make
rapid measurements (within 1 minute or less)
or allow 30 minutes for the unit to stabilize in
the refrigerated environment (above 0°C /
32°F) before measuring. To measure an item
within a storage case, open the door or cur-
tain, and directly scan the product for uniform
temperatures. The presence of warmer areas
may indicate improper stocking resulting in
blocked airflow in the cabinet.
