Abstract

L'appareil permet des mesures fiables et aisées du facteur d'absorptivité, ou d'émissivité infrarouge. A cet effet, l'appareil 1 maintient à température constante et supérieure à la température ambiante les éléments de référence d'une thermopile 5 placée dans une cavité 2 d'un four 7. La variation de tension de l'élément sensible de la thermophile, lorsque l'appareil 1 est disposé sur la surface 9 réfléchissant et émettant les radiations infrarouges à température ambiante, permet de déterminer le facteur d'absorptivité de la surface. L'appareil s'applique à la mesure du facteur d'émissivité ou d'absorptivité infrarouge de tous matériaux et revêtements.
