Abstract
L'invention a pour objet une cellule micro-polarographique pour la mesure de la pression partielle de l'oxygène dans un fluide. La cellule comprend une anode unique en argent, en contact avec un halogénure et une pluralité de cathodes en métal noble impolarisable, les cathodes au moins sont recouvertes d'une pellicule de téflon, perméable à l'oxygène. Si le fluide à analyser ne contient pas d'halogénure, la membrane de téflon recouvre l'ensemble et l'anode est en contact avec un mélange solide d'argent et de chlorure d'argent. L'invention s'applique à des mesures sur les corps vivants.
