| 发明名称 | Reference electrode and ion concentration measurement device | ||
| 摘要 | This invention prevents leakage of an internal liquid and breakage of a reference electrode resulting from volume expansion of the internal liquid due to the congelation of the internal liquid, and comprises a vessel that forms a sealed space, an internal liquid that is contained in the vessel, an internal electrode that is immersed in the internal liquid, an ion conduction part that is arranged on a wall of the vessel and that electrically connects the internal liquid and a measurement sample, and a volume expansion absorption mechanism 6 at least a part of which is immersed in the internal liquid and that absorbs volume expansion of the internal liquid due to congelation of the internal liquid. | ||

| 主权项 | 1. A reference electrode comprising: a vessel that forms a sealed space, an internal liquid that is contained in the vessel, an internal electrode that is immersed in the internal liquid, an ion conduction part that is arranged on a wall of the vessel and that electrically connects the internal liquid and a measurement sample, and a volume expansion absorption mechanism at least a part of which is immersed in the internal liquid and that absorbs volume expansion of the internal liquid due to congelation of the internal liquid, wherein the internal liquid contacts the exterior surface of the volume expansion absorption mechanism, and wherein the volume expansion absorption mechanism comprises an elastic transform part that makes an elastic transformation in accordance with the volume expansion of the internal liquid and a gaseous closed layer that is arranged to make contact with the elastic transform part. | ||
