Abstract
A concentration measurement apparatus includes a sample temperature sensor, optical sensors, an environmental temperature sensor, a storage unit storing second correlation information between first difference information between the environmental temperature and a temperature of a calibration sample, and second difference information between a theoretical temperature based on first correlation information between the temperature and a transmittance of the calibration sample with respect to a measurement value of the transmittance of the calibration sample measured by the concentration measurement apparatus 1 and the measurement value of the temperature of the calibration sample. The apparatus further includes a temperature calibration unit acquiring difference information between a temperature of a target sample and the environmental temperature, and calibrating the temperature measurement value of the measurement target sample by using calibration temperature information based on the second correlation information with respect to the difference information.
