A sensor is constituted by joining a pair of electrodes to a sensor body formed by binding hydrogen occluding metal with binders. Change in the electric resistance between the electrodes and the quantity of hydrogen occluded by the hydrogen occluding metal in the sensor body has a one to one relationship. Therefore, the quantity of hydrogen occluded by the hydrogen occluding metal can be estimated from the resistance value obtained by the sensor.

Apparatus for measuring quantity of hydrogen

There is provided a concentration sensor for measurement of concentrations of one or plural target substances in a system, with a detection electrode of conductive diamond. The measuring method with the concentration sensor involves measuring the reaction potentials of plural target substances in a sample containing and determining the concentrations of the plural substances by use of the difference between the resulting reaction potentials of the respective substances. The measuring method can also determine the concentration of a single substance in a sample containing one kind of target substance.
