Аннотация:A device for testing the percent composition of a two-component mixture of gases with different refractive indices and, therefore, dielectric constants is described. Monitoring is performed by measuring the difference between the values of capacitors, the gap of one of which contains the mixture being analyzed while that of the other contains one of the gases of the mixture. For a mixture of air and Freon-12, their relative concentrations are determined with an accuracy of 0. 3%, which corresponds to an accuracy of relative determination of the refractive index of 7 multiplied by (times) 10** minus **6.
