Abstract

L'invention concerne un dispositif électrochimique pour l'analyse' de fluides. Ce dispositif comprend deux ou plusieurs électrodes en contact avec un réactif qui réagit chimiquement avec le constituant de fluide à détecter et/ou à surveiller de manière à faire passer un courant électrique entre les électrodes, le réactif comprenant une solution aqueuse d'une substance déliquescente. Ce dispositif permet par exemple de détecter rapidement et de surveiller avec précision la présence de substances toxiques telles que du chlore dans des atmosphères respirables ou des courants de gaz de traitement.
