How it Works


How it Works
Infrared thermometers measure the surface temperature of an
object. The unit's optics sense emitted, reflected, and transmit-
ted 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.

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 accura-
cy is critical, make sure the target is at least twice as large as
the spot size.

Distance & Spot Size
As the distance (D) from the object increases, the spot size (S)
of the area measured by the unit becomes larger. See: Fig: 1.

Locating a hot Spot
To find a hot spot aim the thermometer outside the area of in-
terest, then scan across with an up and down motion until you
locate hot spot.
