Gas analysis — Determination of the water dew point of natural gas — Cooled surface condensation hygrometers ISO 6327:1981

Publication date:   Mar 1, 1981

Scope

Describes hygrometers which determine the water content of a gas by detecting water vapour condensation occurring on a cooled surface or by checking the stability of the condensation on this surface. The hygrometers considered here may be used for determining water vapour pressure, without requiring calibration, in a system operating under total pressures greater than or equal to atmospheric pressure.
