Title (EN) DEVICE AND METHOD FOR ELECTROCHEMICALLY SENSING THE PH OF A LIQUID
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTECTION ÉLECTROCHIMIQUE DE PH D'UN LIQUIDE
Abstract:
(EN) The invention presents a device for electrochemically sensing the pH of a liquid using electrolysis, the device comprising: a working electrode; a counter electrode; a current detector arranged to detect a current flowing between the working electrode and the counter electrode;a voltage detector arranged to detect a voltage between the working electrode and the counter electrode; a controller arranged to apply an electrical test sequence to the working electrode and the counter electrode, and to determine the pH of the solution liquid using the detected current and detected voltage during the electrical test sequence. Further, a method for electrochemically sensing the pH of a liquid is presented.
(FR) La présente invention concerne un dispositif pour détecter électrochimiquement le pH d'un liquide par électrolyse, le dispositif comprenant : une électrode de travail ; une contre-électrode ; un détecteur de courant conçu pour détecter un courant circulant entre l'électrode de travail et la contre-électrode ; un détecteur de tension conçu pour détecter une tension entre l'électrode de travail et la contre-électrode ; un dispositif de commande conçu pour appliquer une séquence de test électrique à l'électrode de travail et la contre-électrode, et déterminer le pH de la solution liquide en utilisant le courant détecté et la tension détectée pendant la séquence de test électrique. En outre, l'invention concerne un procédé pour détecter électrochimiquement le pH d'un liquide.
