Two kinds of mass-filter probe are applied to measurements of the pressure and velocity ratios in rarefied flows of gases mixture. One is a type of static pressure probe and the other a type of total pressure probe. The free molecule flow theory provides the component pressure and velocity ratios in terms of the signals detected by the two types of probe. Comparison of the results with those by the previous electron-beam technique is made for both swirling flow of He/N_2 mixture and free jet of He/N_2 (or He/Ar) mixture. The agreement is fairly good in a moderate pressure region except comparatively lower pressure region.
