The emission degrees listed in the table are approximates. Various parameters, such as geometry and surface qual-

ity, may influence the emission degree of an object.
The meter is delivered with a pre-set emission degree of 0.95. It matches for most non-metal materials. The IR 

measuring method is only conditionally suitable for blank metals and requires  

special surface treatment (e.g. matte insulating tape, etc.) or pre-setting of the corresponding emission degree.
