Abstract

Deux électrodes 6, 7 en un même matériau sont en contact en 4, 5 avec un électrolyte, une des électrodes est réalisée de façon que le gaz arrive à la limite de phase électrode-électrolyte, et le signal électrique émis par l'élément indique la quantité précitée; suivant l'invention seconde électrode est réalisée et disposée comme la première, au voisinage d'une électrode 6, l'électrolyte est mélangé en 4 à des adjuvants qui ne réagissent qu'au gaz nuisible à doser, et des moyens 3 empêchent les adjuvants et les produits de la réaction précitée d'arriver à l'autre électrode 7.
