PROBLEM TO BE SOLVED: To provide a detection device which automatically sets a proper threshold at all times even in a case where a proper threshold has not been set due to a setting error and the like of a user, or a case where the output level of a sensor is decreased due to condensation or a stain in a measurement system or degradation or the like of the sensor, thereby reducing omission of detection and detection errors.SOLUTION: The detection device comprises: threshold setting means 7 capable of obtaining a threshold on the basis of a first calibration value and a second calibration value, and storing the threshold in storage means 4; and threshold resetting means 8 capable of comparing the first calibration value with an output value of the sensor at the time when a sample to be measured is measured, to obtain a threshold to be reset according to a difference between the output value and the first calibration value and reset (correct) the threshold value stored in the storage means 4. |
