Abstract
A temperature measuring method and device is capable of measuring temperature of a gas, and particularly temperature of a gas that contains water vapor, in a non-contact manner and with good precision. A spectroscopic unitacquires at least a light intensity in a first wavelength band and a light intensity in a second wavelength band, from radiated light from water vapor that is an object to be measured. The first wavelength band and the second wavelength band are both near infrared region bands. A central wavelength of the first wavelength band and a central wavelength of the second wavelength band are set to be mutually different values. A temperature calculation unit calculates temperature of water vapor using a ratio of light intensity in the first wavelength band to light intensity in the second wavelength band.
