Abstract

La présente invention concerne un appareil pour mesurer une concentration de chlore résiduel, comprenant : une partie de mesure comportant une partie d'émission de lumière et une partie de réception de lumière, et comportant un tube d'entrée d'eau d'échantillon dans lequel l'eau d'échantillon s'écoule ; une partie de stockage de réactif constituée d'un matériau rétractable de façon à injecter un réactif dans la partie de mesure, et comportant un tube d'entrée de réactif ; et une partie de commande pour mesurer la concentration d'un oxydant dans l'eau d'échantillon sur la base d'un signal généré lorsque la lumière générée par la partie d'émission de lumière traverse l'eau d'échantillon et est ensuite reçue dans la partie de réception de lumière, de façon à simplifier une structure de façon à améliorer la durabilité, et réguler la quantité de réactif injectée.
