The measurement apparatus in the National Primary Standard for the units of relative humidity of gases, molar (volume) fraction of moisture, and temperature of the dew/frost point, GET 151-2014, is described. The metrological characteristics of the standard and the results of the international key comparison CCT-K6 are described.
