Abstract
A thermometer comprises an emitting unit, a light receiving unit, a light collecting unit, and a calculation unit. The emitting unit is configured to emit a measurement light into a flue, wherethrough a gas that contains light scattering particles flows. The light receiving unit is configured to receive, of the measurement light, scattered measurement light scattered by the light scattering particles. The light collecting unit is configured to collect the scattered measurement light existing on the light receiving axis. The calculation unit is configured to calculate the temperature inside the flue based on an intensity ratio of absorption spectra at a plurality of wavelengths.
