How does an infrared thermometer work?

Each object transmits infrared rays. The power of these rays depends on the type 

of material (expressed as “radiation coefficient” or “emissivity” of a material) and of 

course the temperature of the object. An infrared detector absorbs these rays and the 

electrons in the device turn them into temperature (° C or ° F).

This thermal camera shows the temperature of all objects in the vicinity on a thermal 

image (color scale with, for example, blue is cold and red is warm). This camera can 

mix the thermal image with an optical image. This will make the measuring area more 

visible and you can understand where a cold or hot spot is exactly. 

Radiation coefficient or emissivity

The amount of infrared energy radiated by an object is proportional to the tempera-

ture of the object and the ability of the material to radiate energy. This ability refers 

to “radiation coefficient” or “emissivity”. Emissivity is the ratio of the average emission 

power to a black radiator at the same temperature. Emission is for most materials 

between 0.10 and 1.00. Materials with low emissivity (<0.60) emit little energy, typi-

cally for materials with a shiny, light surface (eg metals). Materials with high emissivity 

(>0.90) emit much energy, typically for matte dark areas. The lower the emissivity, the 

more difficult it is to accurately measure.

This thermal camera has the ability to set the emissivity of the meter object from 0.10 

to 1.00. If you set the correct radiation coefficient, you will measure more accurately. 

Look for the correct value in the table next to it. In case of doubt, use 0.95, which can 

be used for 90% of applications.
