Aluminum poses a real challenge when it comes to temperature measurement. These non-greybody materials have a low emissivity that varies by wavelength, which makes accurate and repeatable temperature measurements nearly impossible with traditional single-wavelength and ratio pyrometer technologies. If you’re looking for a reliable aluminum infrared temperature sensor solution, multi-wavelength technologies are far better suited for the application.
