Abstract

The invention provides for a dynamic dew point analysis method as well as an apparatus for carrying out the method wherein the method comprises: arranging a moisture containing gas in the immediate vicinity of at least two thermocouples, where one thermocouple is shielded from the gas; creating an analogous temperature change in both thermocouples and registering the temperature in both thermocouples during a cycle where the condensation point of the moisture containing gas is passed, using the different temperatures from the at least two thermocouples as input for determining the dew point according to basic thermodynamic principles.
