APPARATUS FOR MEASURING DEW POINT ON-LINE AND METHOD THEREFOR

摘要

PURPOSE: A method for measuring a dew point is provided to secure a quality through an appropriate adjustment of humidity of a production process line by measuring a dew point on-line. CONSTITUTION: A moisture content is measured in a state of saturated vapor pressure of sampled gas, and a dew point is calculated. A ratio of main molecular weight to a relative amount is calculated in measuring the content with respect to water molecules, and a measurement of the moisture content is carried out by a standardized formula regardless of a volume of the sampled gas picked by an automatic gas sampling unit(50), to thereby secure a quality reproduction through an appropriate adjustment of humidity of a production process lien by measuring a dew point on-line.
