The ET100 measures directional reflectance at six bands in the thermal infrared spcetral region at two incidence angles, 20¡Æ and 60¡Æ. Based on those values, directional and total hemispherical emissivity is calculated. It is a real portable battery powered reflectometer controlled by a built in PDA type computer. The ET100 is a handy tool for radiative heat transfer applications including field inspections.
