The method of gas chromatography is adopted in the invention, and the technique of separation concentration is utilized in the sampling system. Thus, the moisture of the sampled gas in the evaporating column is condensated in the low temperature so as to separate out SF6 gas. The residual SF6 in the evaporating column is driven away by the carrier gas. Then, warming up the evaporating column to vaporize the moisture, which passes through the chromatographic column and the detector so as to measure the humidity water-content. Comparing with the prior art such as the electrolytic method, the resistance-capacitance method and the dew point method, the invented method possesses the advantages of low air consumption and high accurate degree.
