Abstract

Appareil pour déterminer le taux d'une substance donnée dans un gaz, par passage d'un volume déterminé de ce gaz dans un réceptacle contenant une matière ayant une réaction colorée avec la substance. Cet appareil comporte une chambre (6) déformable d'un volume donné pouvant être mise en communication soit avec un conduit d'arrivée de gaz (10), soit avec un conduit débouchant à l'extérieur par l'intermédiaire du réceptacle (14) contenant le réactif coloré (15), une source lumineuse (18) placée en regard du réactif coloré, un capteur photoélectrique (19) également placé en regard du réactif coloré, la source lumineuse et le capteur étant disposés de manière que la lumière provenant de la source lumineuse ne puisse parvenir au capteur qu'après avoir franchi le réactif coloré, un indicateur (21) affichant le courant du capteur, donc la quantité de lumière ayant traversé le réactif (15), et des moyens pour faire passer un volume de gaz donné dans le réceptable.
