<p>A device for measuring ion activity comprising two multilayer ion-selective half cells in flat form which are arranged on a supporting frame and electrically insulated from each other and which are provided with ion-selective membrane as the outermost layer; a porous bridge capable of absorbing and retaining an aqueous liquid which is arranged in such a manner that said porous bridge covers at least a portion of said both outermost layers of the half cells, and a dry and water-soluble salt provided in the region from the surface of a outermost layer on one of the half cells to the porous bridge on said half cell. A method for measuring ion activity using the device is also disclosed.</p> |
