Abstract
An air sampling device and method of sampling air. The device has a housing body and a retaining assembly for a sampling device. A plenum has a top end coupled to the housing body about an opening such that the plenum is in flow communication with the opening and receives air flow generally from the top end to the bottom end generally along the longitudinal length thereof. A flow connection is coupled to the bottom end of the plenum. A mass flow meter has an input coupled to the flow connection and is in flow communication with the plenum via the flow connection. A blower is configured to draw air past the sampling device, through the opening, and through the plenum, such that a measuring portion of the air flows through the flow connection and through the mass flow meter, which measured the flow rate of the measuring portion.
