Abstract: A portable instrument for the rapid, volumetric determination and recording of the less than 1- to over 100-micron particle content in atmospheres is described. Dust is collected by impingement on a moving ribbon of acetate film. Optical density is measured at the site of deposition on the ribbon and recorded. Constancy of air flow and positioning of the ribbon with respect to the orifice are controlled by the application of aerodynamical principles. Provision is made for the visual viewing of the deposit under the orifice. Ribbon speed is controllable to allow for wide ranges of dust concentration.
