The utility model discloses a silver-silver chloride reference electrode, the electrode tube (1) is filled with a reference solution, the bottom of the electrode tube (1) is provided with a liquid interface (4), the side of the electrode tube (1) is provided with a liquid feeding port (3), the electrode tube (1) is also provided with a lower opening capacity tube (10), The capacity tube (10) is arranged from bottom to top with an electrode filling layer (6), silver chloride powder layer (7), silver powder layer (8), the lower end of the metal wire (11) resistance is extended into the silver powder layer (8), and the upper end is connected with the electrode lead. There is no silver chloride coating in the reference electrode, so it will not be dissolved by potassium chloride solution at either low or high temperature. Therefore, the temperature range of the reference electrode is expanded, and the blockage of the liquid interface can be prevented, the measurement accuracy is good, and the service life is long.
