'''玻璃电极'''（glass electrode），是用对[[氢离子]]活度有[[电势]]响应的玻璃薄膜制成的[[膜电极]]，是常用的[[氢离子指示电极]]。

它通常为圆球形，内置0.1mol/L盐酸和[[氯化银电极]]或[[甘汞电极]]。使用前浸在纯水中使表面形成一薄层[[溶胀]]层，使用时将它和另一[[参比电极]]放入待测溶液中组成电池，电池电势与溶液pH值直接相关。由于存在不对称电势、[[液接电势]]等因素，还不能由此电池电势直接求得pH值，而采用[[标准缓冲溶液]]来“标定”，根据pH的[[定义式]]算得。玻璃电极不受氧化剂、[[还原剂]]和其他杂质的影响，pH测量范围宽广，应用广泛。
