PROBLEM TO BE SOLVED: To provide a dissolved hydrogen detector and dissolved hydrogen detection method allowing anyone to easily and reliably detect a dissolved hydrogen at any time.SOLUTION: A test solution containing an oxidation-reduction pigment is held in a package body having a hydrogen permeable film, thereby forming a dissolved hydrogen detector. The dissolved hydrogen detector is brought into contact with an analyte and color change of the oxidation-reduction pigment is detected, thereby detecting the dissolved hydrogen. Preferably, the test solution further contains a catalyst for increasing the reactivity of the oxidation-reduction pigment. |
