标准摘要
[中文适用范围]： 描述了通过检测冷却表面上发生的水蒸气凝结或通过检查该表面上凝结的稳定性来确定气体的水含量的湿度计。 这里考虑的湿度计可用于在总压力大于或等于大气压力下运行的系统中确定水蒸气压力，而不需要校准。 [外文原描述]： 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.
英文名称Gas analysis — Determination of the water dew point of natural gas — Cooled surface condensation hygrometers
