The measurement methods and instrumentation for the national primary standard for the units of relative humidity of gases, molar (volume) fraction, and temperature of the dew point, GET 151-2014, are discussed. The structure of the standard is described. The metrological characteristics of the standard and the results of the international key comparisons CCT-K6 are reported.
