FIELD: devices for metering-out of admixtures into gas flow for testing detectors of gas admixtures in their operation and in solving problems of gas analysis. SUBSTANCE: device has replaceable sources of volatile admixtures installed in sockets of switching cock which is connected with flow branches to sources through regulator which body is separated by bushing with movable rod to form channel of varying cross-section. Sources are made in the form of bow from fluoroplastic tube accommodating core with admixture. EFFECT: improved design. 2 cl, 2 dwg
