Abstract:
1. A disposable electrolyte test in the form of a substantially flat package, the electrolyte test comprising: a. a flat, planar substrate; b. a sample-receiving region on the substrate; c. an ion-sensor cartridge in fluid communication with the sample-receiving region, the ion-sensor cartridge comprising an ion-selective layer for passing only certain species of a sample to an electrode layer; d. an indicator on the substrate adjacent the sample-receiving region, wherein the indicator comprises a plurality of indicator elements for indicating a concentration level of an electrolyte within the sample; e. circuitry for operating the ion-sensor cartridge and the indicator so as to cause display, on the indicator, of an ionic parameter in response to the presence of the sample on the sample-receiving region; and f. a flexible cover affixed over the substrate so as to be unsealable therefrom and to thereby expose the sample-receiving region, wherein the disposable electrolyte test is configured to conformably affix to a curved surface of a fluid container.
