Abstract
An improved electrode assembly for measuring ions, such as a pH electrode, and method of forming the same is provided. A plastic support layer with an aperture is mounted over a base member having electrodes. A gelatinized internal solution is mounted in the aperture over the electrodes in a plasticized solution containing a hydrogen ion-responsive material is formed into a paste and is positioned over the gelatinized internal solution and the adjacent surrounding areas of the support layer. When the paste solidifies it forms a thin film plastic ion-selective response membrane that is integrally sealed to the support layer.
