Abstract
La présente invention a pour objet un appareil de mesure de la teneur en oxygène dans de l'eau comprenant, d'une part, une électrode de mesure à introduire dans un échantillon d'eau, électrode qui engendre un signal de sortie dépendant de la teneur en oxygène de l'échantillon, et, d'autre part, un ensemble indicateur qui est relié électriquement à l'électrode de mesure et qui reproduit, sous forme d'indications lisibles, le signal engendré par ladite électrode de mesure. Selon l'invention, l'électrode de mesure et l'ensemble indicateur sont reliés mécaniquement l'un à l'autre pour former une canne de mesure manoeuvrable comme un ensemble unitaire
