  • Hydrogen concentration measuring device
    Patent number: 10302612
    Abstract: Provided is a hydrogen concentration measuring device capable of measuring with high accuracy a hydrogen concentration over an extensive range by a simple configuration. The device includes: a sensor chip which detects the electric resistance of a sensing film; an optical measurement unit which detects the transmitted light intensity of the film; and a controller. The controller performs measurement processing such that a hydrogen concentration in the gas atmosphere is measured based on the detected electric resistance in a first measurement range and based on the detected transmitted light intensity in a second measurement range and is determined so as to reduce a difference between the hydrogen concentration based on the detected electric resistance and the hydrogen concentration based on the detected transmitted light intensity in the overlap of the first measurement range and the second measurement range.
