Method and device for the simultaneous measurement of particulate matter concentrations PM1, PM2.5 and PM10 - Particulate Matter

摘要

In a method of simultaneously measuring and displaying various particulate matter concentrations in a two phase orbit current using a pulsed photometric stray light unit comprising a light emitter emitting pulsed light signals and an angled receiving photosensitive receiver system which detects the scattered light of the Particles receives, wherein the flow of the fluid to be examined usually with a right angle to the light emitting unit and light receiving unit, it is provided that the scattered light unit is hermetically sealed with measuring volume.
