  Cove a part of the surface of the measuring object with black, flat paint with an emissivity of 0,98. Adjust the 

emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface. Afterwards, 
determine the temperature of a directly adjacent area and modify the emissivity until the measured value 

corresponds to the temperature of the colored surface. 

 

Characteristic Emissivities 

 

In case none of the methods mentioned above help to determine the emissivity you may use the emissivity 
tables (Appendix A and B). These are average values, only. The actual emissivity of a material depends on the 

following factors: 

ƒ

 

temperature 

ƒ

 

measuring angle 

ƒ

 

geometry of the surface 

ƒ

 

thickness of the material 

ƒ

 

constitution of the surface (polished, oxidized, rough, sandblast) 

ƒ

 

spectral range of the measurement 

ƒ

 

transmissivity (e.g. with thin films)
