IR (Infrared) Thermometer Measurement Considerations
The object under test should be larger than the spot (target) size calculated by the field of view
diagram.
If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking
measurements.
If an object's surface is highly reflective, apply masking tape or flat black paint to the surface
before measuring.
The meter may not make accurate measurements through transparent surfaces such as glass.
Steam, dust, smoke, etc. can obscure measurements.
The meter compensates for deviations in ambient temperature. It can, however, take up to 30
minutes for the meter to adjust to extremely wide ambient temperature changes.
To find a hot spot, aim the meter outside the area of interest then scan across (in an up and
down motion) until the hot spot is located.
IR measurements cannot be made through glass.
IR (Infrared) Thermometer Field of View
The meter’s field of view is 8:1. For example, if the meter is 16 inches from the target (spot), the
diameter of the target must be at least 2 inches.
Note that measurements should normally be made less than 2 feet from the target. The meter can
measure from further distances but the measurement may be affected by external sources of light.
In addition, the spot size may be so large that it encompasses surface areas not intended to be
measured.
