Abstract: A calibration apparatus for a chemical sensor may include a conversion calculation unit that acquires a measurement value of a calibration solution that is measured by the chemical sensor and calculates a conversion calculation output, a calibration sensitivity extraction unit that receives the conversion calculation output and extracts a calibration sensitivity from the conversion calculation output, a calibration history storage unit that stores past histories of the calibration sensitivity, and a sensitivity variation curve prediction unit that predicts a sensitivity variation curve based on the past histories of the calibration sensitivity, the sensitivity variation curve prediction unit calculating a sensitivity correction value based on the sensitivity variation curve, the sensitivity variation curve prediction unit supplying the sensitivity correction value to a sensitivity correction part that performs a sensitivity correction in a measurement apparatus.
