To develop a dissolved hydrogen sensor which can be simply and stably used over a long period of time, can be made small-sized and enables a person other than an expert to handle a dissolved hydrogen sensor, and is used for a new technique for measuring the concentration of dissolved hydrogen in water, a device and an apparatus.
The dissolved hydrogen sensor has a hydrogen responding body, which comprises a metal material reversively changed in physical property value by the occlusion and discharge of dissolved hydrogen, as a sensor element and is constituted so as to detect the presence or concentration of dissolved hydrogen in water by measuring a change in the physical property value of the sensor element. A dissolved hydrogen detector is equipped with the dissolved hydrogen sensor. The hydrogen responding body comprises the metal material changed in the physical property value reversively by the occlusion and discharge of dissolved hydrogen. A technique for detecting and measuring dissolved hydrogen by utilizing the reversible change in the physical property value of the hydrogen responding body with respect to dissolved hydrogen and a means therefor are also disclosed.
