Abstract
A test kit for gas detectors is disclosed, including an aerosol can containing a predetermined gas mixture of predetermined concentration and a pierceable conduit having first and second open ends, the first open end being adapted to engage an inlet opening of the gas detector. The pierceable conduit further includes a plug having an orifice therethrough for admitting small amounts of air into an interior of the conduit. The plug is located in the conduit adjacent the second open end. A hollow needle is adapted to engage an outlet valve on the aerosol can, and the needle is manipulated to pierce the conduit, delivering the predetermined gas mixture of predetermined concentration to the gas detector.
