The present invention relates to devices, methods, and kits for quickly and easily measuring and monitoring the pH of aquatic environments, such as lakes, streams, drinking waters, fisheries, aquariums, pools, hot-tubs, and spas. The current invention includes devices that are reusable and capable of monitoring the pH in a reversible fashion, thereby allowing continuous pH sensing without a need for the user to physically perform pH tests. Operation of the invention involves placing the device into the aquatic environment and optically detecting a color change in the membrane, for example, by looking at the device, when a pH measurement is desired. In addition, the device is both inexpensive and reusable, allowing the user to monitor the pH of various aquatic environment at minimal costs.

L'invention concerne des dispositifs, des procédés, et des kits permettant de mesurer et de contrôler facilement et rapidement le pH d'environnement aquatiques, de type lacs, ruisseaux, eaux de boisson, pêcheries, aquariums, piscines, bains à remous, et spas. L'invention propose des dispositifs qui sont réutilisables et qui permettent de contrôler le pH de façon réversible, la détection du pH pouvant ainsi être assurée en continu sans intervention physique de l'utilisateur pour la mesure du pH. La mise en oeuvre de l'invention consiste à positionner le dispositif dans l'environnement aquatique et à détecter de manière optique un changement de couleur dans la membrane, par exemple, par visualisation du dispositif, lorsqu'une mesure de pH est désirée. En outre, le dispositif est peu onéreux et réutilisable, ce qui permet à l'utilisateur de contrôler le pH de divers environnements aquatiques à des coûts minimes.
