Abstract

La présente invention concerne un dispositif pour mesurer la pression partielle de gaz dissous dans des liquides. Ce dispositif comporte (a) un point de mesure (15) qui est partiellement isolé par une membrane perméable aux gaz (11), laquelle est perméable au gaz à déterminer; (b) une source d'émission lumineuse (6) pour produire un faisceau lumineux assurant une interaction avec le liquide dans le point de mesure (15) et présentant une longueur d'onde qui est absorbée par le gaz à déterminer; et (c) un système de mesure (7) permettant de déterminer la lumière quittant le point de mesure (15). Ce dispositif est caractérisé en ce que (d) le point de mesure (15) est en contact avec l'interface d'un élément photoconducteur (14), et (e) la lumière est guidée à travers ledit élément (14) de telle manière que sa réflexion totale est affaiblie au niveau de l'interface.
