EMS 

In this section, it is possible to set the values of parameter 

Emissivity

 of the material of 

the object to be measured. In order to carry out accurate temperature measurements, it is 
important to define the correct emissivity value (

), which represents the ability of a body to 

emit infrared radiation, according to the kind of material the measured object is made of. 
Table 1 shows the emissivity values for the most common materials. Emissivity takes 
values between 0 (mirror or perfectly reflecting surface) and 1 (perfectly radiating black 
body). Most of the painted or oxydized surfaces have an emissivity value of approximately 
0.95.
