摘要： A reusable device for continuously monitoring gaseous ammonia concentration in a surrounding environment comprising a plurality of layers, including an active layer in which a dye (e.g., an indicator dye useful for measurement of pH) is immobilized to a membrane (e.g., polyamide membrane), and a hydrophobic filter layer capable of permitting contact between the active membrane and dissolved gaseous ammonia.

摘要： 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.
摘要翻译：本发明涉及用于快速且容易地测量和监测诸如湖泊，溪流，饮用水，渔业，水族馆，游泳池，热水浴缸和水疗中心等水生环境的pH的装置，方法和试剂盒。本发明包括可重复使用并且能够以可逆方式监测pH的装置，由此允许连续的pH感测，而不需要用户物理地进行pH测试。本发明的操作涉及当需要pH测量时，将装置放置在水中环境中并且通过观察装置来光学地检测膜中的颜色变化。此外，该设备既便宜又可重复使用，允许用户以最低的成本监测各种水生环境的pH值。
