Multispectral radiation thermometry (MRT) using two commonly used emissivity models, linear emissivity models (LEM) and log-linear emissivity models (LLE), was used to predict the aluminum surface temperature. Experiments were conducted to measure the spectral intensity values for five different aluminum alloys at three different temperatures. Overall, three emissivity models give good results most frequently and provide the best compensation for different alloys, the number of wavelengths, temperatures, and heating time.
