Since the emissivity of a material will vary as a function of temperature and surface … Webspecific IR sensor. In this work, two IR cameras with different spectral bands are used: FLIR SC6000 (InSb detector with a 3-5 µm spectral band) and FLIR SC640 (uncooled microbolometer detector with 7.5-13 µm spectral band). A method for wall emissivity measurement in-situ is proposed. The test is easy to be performed and it takes only
