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 also includes 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. The collection device is positioned downstream of the real-time measuring device.
