Describes automated instrumentation using sulphur hexafluoride as a tracer gas in residential housing to determine rates of air infiltration in houses. Discusses in detail the principles of operation, necessary calibration procedures and early field data. Concentration levels of SF6 are maintained at the partsper million level in the buildings and are measured by sensitive electron capture detectors in conJunction with a gas chromatograph.
