Workplace exposure. Guide for the use of direct-reading instruments for aerosol monitoring - Evaluation of airborne particle concentrations using photometers Ingestion-build-48068 signal blocking at a predetermined1 Scope This Technical Report describes the use of photometers for the determination of airborne particles belonging to the respirable fraction and gives details on their limitations and possible uses in the field of occupational hygiene. NOTE Photometers can also be used to detect other size fractions of airborne particles after aerodynamic pre separation, but these are not the focus of this Technical Report. The method complements existing
