    • A gas sensor includes a multi-layered solid-state pH electrode and a reference electrode coated with a gas-sensitive layer (solid-state or gel-state) sensitive to an ion of interest, the surface of the combination being coated with a gas-permable layer. Also provided in a gas sensor having a pH electrode and a reference electrode immersed in a gas-sensitive solution within a gas-permeable layer. Preferably, a fixed distance is maintained between a sensitive portion of the pH electrode, a sensitive portion of the reference electrode and the gas-permeable layer isolated by means of a porous layer. In another embodiment, the gas sensor incorporates a common electrode and a thermister for temperature calibration.
    • 气体传感器包括多层固态pH电极和涂覆有对感兴趣的离子敏感的气敏层(固体或凝胶状态)的参比电极,该组合物的表面被涂覆有气体 可编程层。 还设置在具有浸入透气层内的气敏溶液中的pH电极和参考电极的气体传感器中。 优选地,在pH电极的敏感部分,参考电极的敏感部分和通过多孔层分离的透气层之间保持固定的距离。 在另一个实施例中,气体传感器包括用于温度校准的公共电极和热敏电阻。
