摘要：PROBLEM TO BE SOLVED: To enable the extent of drift occurrence in the output of a COsensor to be diagnosed.SOLUTION: A COsensor diagnosis device 20 comprises: a COconcentration measured value acquisition unit 21 for acquiring a COconcentration measured value from a plurality of COsensors, and finding the minimum value of COconcentration measured values in a prescribed period for each sensor; a COconcentration classification unit 22 for classifying the minimum value of COconcentration measured values of each COsensor into a plurality of COconcentration ranges based on a predetermined COconcentration value; and a sensor diagnosis unit 23 for diagnosing the extent of drift occurrence in the output of each COsensor from the result of classification by the COconcentration classification unit 22.SELECTED DRAWING: Figure 2
