Interim Report on the Continuous Injection Air Infiltration Measuring Device; LOCATION = North America;

This report contains a brief description of an air infiltration measuring device jointly developed by the National Bureau of Standards and Princeton University's Center for Environmental Studies. The device maintains a constant concentration of a tracer gas (SF6) in each room of a structure by injection, and relates the infiltration rate for each room to the rate of gas injected. Specifics of construction and use are included.
