<P>PROBLEM TO BE SOLVED: To accurately calibrate a hydrogen sensor system. <P>SOLUTION: A hydrogen sensor system includes: a hydrogen detection element showing output according to hydrogen concentration in the atmosphere; a storage means for storing association data for associating the output of the hydrogen detection element with the hydrogen concentration; and a control means for converting the output of the hydrogen detection element into the hydrogen concentration based on the association data, in which the control means performs zero point correction for correcting deviation of a zero point showing characteristics when the hydrogen concentration is zero based on the output measured at predetermined timing that the atmosphere of the hydrogen detection element can be considered as an atmospheric state (step S4), and adjusts ratio of the hydrogen concentration to the output based on a parameter relevant to a deterioration degree of the hydrogen detection element (step S6). <P>COPYRIGHT: (C)2012,JPO&INPIT |
