ABSTRACT:
Apparatus and method for measuring the concentration of airborne fibers are provided. The apparatus includes a flow channel for providing laminar flow to a portion of the fibers in an air sample and a light source for generating a light beam directed to the laminarly flowing fibers to produce a scattered light. The apparatus further includes a sensor for sensing a portion of this scattered light and for producing an output from which a fiber concentration estimate can be measured.
