Appendix: Emissivity Chart
Emissivity is a term used to describe the energy-emitting characteristics of
materials. Most (90% of typical applications) organic materials and painted
or oxidized surfaces have an emissivity of 0.95.
Inaccurate readings will result from measuring shiny or polished metal
surfaces. To compensate, cover the surface to be measured with masking
tape or at black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or
painted surface.
