摘要：Emissivity is a key parameter if one intends to use quantitative thermography. The importance of temperature, surface characteristics, wavelength and the direction of the emitted radiation in the emissivity is well documented in the literature. However, no research was found concerning the effect of moisture content. In this research, an experimental campaign was carried out with two main objectives: compare the emissivity value measured with an emissometer with the value measured with infrared thermography; assess the importance of moisture content in the emissivity value measured with an emissometer. A ceramic brick was used as an example case.
