8. Notes
8-1. How it Works
Infrared thermometers measure the surface temperature of an object. The
unit's optics sense emitted , reected, and transmitted energy, which is collected
and focused onto a detector. The unit's electronics translate the information into a
temperature reading which is display on the unit. In units with a laser, the laser is
used for aiming purposes only.
8-2. Field of View
Make sure that the target is larger than the unit's spot size. The smaller the
target, the closer you should be to it. When accuracy is critical, make sure the
target is at least twice as large as the spot size.
8-3. Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area
measured by the unit becomes larger.
8-4. Locating a hot Spot
To nd a hot spot aim the thermometer outside the area of interest, then scan
across with an up and down motion until you locate hot spot.
8-5. Reminders
• Not recommended for use in measuring shiny or polished metal
surfaces (stainless steel, aluminum, etc.).
• The unit cannot measure through transparent surfaces such as glass.
It will measure the surface temperature of the glass instead.
• Steam, dust, smoke, etc., can prevent accurate measurement by
obstructing the unit's optics.
