Abstract : This patent describes a particulate sampling probe comprising an L-shaped protective tube of circular cross-section, and an intermediate tube and an inner collecting tube both of circular cross-section and concentrically disposed therein. The protective tube has an opening in one end permitting the entry of particulates into the collecting tube which communicates with the opening. A suction pump pulls particulates into the collecting tube. Exhaust from the collecting tube passes through a particulate collector, the pump, and a gas meter. After a test, the preweighed collecting tube is removed from the protective tube and weighed. The difference between the pretest and posttest weights of the collecting tube and collector is a measure of the amount of particulates that has been sampled.
