IMPROVED DEVICE FOR MEASURING THE CONCENTRATION OF AIRBORNE FIBERS |
摘要 |
Devices and methods for measuring the concentration of airborne fibers are provided. The devices include flow means 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 device further includes a sensor for sensing a portion of this scattered light and for producing an output from which a respirable fiber concentration estimate can be measured. |
