Abstract
A gas sensor system includes a first pipe through which a specimen atmosphere is conveyed; a second pipe through which humidified air is conveyed, the humidified air being hotter and more humid than the specimen atmosphere, the humidified air having a lower water vapor pressure than a saturation water vapor pressure; a mixing device mixing the specimen atmosphere and the humidified air so that a water vapor pressure of mixed air of the specimen atmosphere and the humidified air is less than a saturation water vapor pressure; a third pipe connected with the mixing device; a cooling device cooling the mixed air conveyed through the third pipe so that the water vapor pressure of the mixed air becomes the saturation water vapor pressure; and a chemical sensor device including a sensor surface to which the mixed air cooled by the cooling device is supplied.
