Zusammenfassung:	The present invention relates to a method for measuring the humidity of a constant flowing sample gas of a combustion process. The method comprises the steps of transporting (B) the sample gas at a specific temperature above the dew point temperature to a cooling-region (24) having a temperature equal to or lower than a temperature at which water vapour in the sample gas condenses, cooling (C) the sample gas in this cooling-region (24) to at least the condensation temperature, so that water vapour condenses and purging the condensate (34), determining (D) the temperature of a position in a condensation-region (40) of the cooling-region (24), and calculating (E) the humidity content of the sample gas based on the determined temperature of the position in the condensation-region (40) of the cooling-region (24) using calibration data.
