Abstract
A particulate monitor includes a housing, an air-moving device coupled to the housing, and an air passageway disposed at least partially within the housing. The air-moving device is operable to create an airflow through the air passageway. The particulate monitor may include a real-time measuring device positioned at least partially within the housing and in fluid communication with the air passageway and a particulate collection device positioned at least partially within the housing and in fluid communication with the air passageway. A collection device may be positioned downstream of the real-time measuring device. At least one impactor may be movably coupled to the housing to be movable between a first position adjacent the air passageway and a second position displaced from the air passageway.
