6.1.5. Emissivity...
Emissivity
The emissivity describes the capability of a body to emit
electromagnetic radiation. This is material-specific and must be
adapted for correct measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings),
plastics and food have high emissivity, which means that the
surface temperature can be easily measured using infrared.
Because of their low or non-uniform emissivity, bright metals and
metal oxides are only somewhat suited for infrared measurement.
You must anticipate highly inaccurate measurements. A remedy for
this is coatings that increase the emissivity, e.g. paint or emission
adhesive (art. no. 0554 0051) which must be applied to the object
being measured.
