Aluminum and other non-ferrous metals like copper and bronze are notoriously difficult materials to measure using infrared technology. The reason is that these metals are non-greybody materials – meaning that they have a low emissivity that varies by wavelength. Accurate and repeatable temperature measurements are nearly impossible with traditional single-wavelength and ratio pyrometer technologies. However, Multi-Wavelength technologies with application-specific algorithms automatically adjust and compensate for these varying emissivity conditions.
