Abstract

L'invention concerne un réflectomètre portatif pourvu d'une tête de mesure qui comprend un élément tronconique 1a dont la petite base est tournée vers l'échantillon à mesurer et dont la grande base se raccorde à un élément cylindrique coaxial 1. Ce réflectomètre comporte une source lumineuse 24 disposée sur l'axe de la tête à l'intérieur dudit élément tronconique et à proximité immédiate de sa petite base, de manière à ce que le flux lumineux réfléchi par ledit échantillon passe dans la zone entourant la source lumineuse et traverse ensuite un disque en matière plastique transparente 16, un filtre interférentiel 12 et une photopile 10. Mesure de réflectance des viandes.
