Abstract

L'invention concerne les appareils de contrôle et de mesure. L'appareil faisant l'objet de l'invention est caractérisé en ce que le canal de transmission au photorécepteur 4 d'une partie du flux lumineux provenant de l'illuminateur 3 comporte deux miroirs 14 et 15, disposés respectivement à l'intérieur de la chambre 1 sur, respectivement, l'axe optique de l'illuminateur 3 et l'axe optique du photorécepteur 4, en aval (suivant le sens du flux lumineux), du point d'intersection de ces axes optiques le diaphragme 16 et la vanne mécanique étant disposes entre lesdits miroirs, et ladite vanne mécanique 17 étant réalisée sous forme d'une tige actionnée par une commande 18 de mouvement en va-et-vient. L'invention s'applique notamment à l'étude de la composition de la phase dispersée des aérosols ou de poudres préalablement dispersées dans l'air.
