Abstract: A device and method for measuring humidity of a constant flowing sample gas of a combustion process includes transporting the sample gas at a specific temperature above the dew point temperature to a cooling-region having a temperature equal to or lower than a temperature at which water in the sample gas condenses, cooling the sample gas in the cooling-region to at least the condensation temperature, so that water condenses, purging the condensate, determining the temperature of a position in a condensation-region of the cooling-region, and calculating the humidity content of the sample gas based on the determined temperature using calibration data.
