Abstract
This paper proposes the technique to measure the band emissivity using the infrared detector with a band pass filter of 7.5 to 14 um. The experimental setup consists of an infrared camera, K-type contact thermocouples, a tripod, a water bath, aluminium plate, a black tape, and an environmental control chamber. Three types of reflective engineering materials including aluminium, stainless steel, and copper are tested using this technique. Results are in good agreement with the findings from other literatures. Therefore, the proposed technique, which is easy to operate, can be an alternative method for measuring the emissivity of reflective materials. However, care must be taken in selecting the location the infrared camera, the material for lining internal surface of an environmental control chamber, and the temperature of chamber surface.
