The BPM-200 PM10 monitor measures PM10 using well-established beta-ray attenuation technology.
Particulate matter sample is pulled by a vacuum pump and concentrated on filter tape spot, the concentrated sampleis advanced to measuring position where between beta raysource and detector. An attenuation signal of beta ray is detected which represents the mass of sample particulate.Particulate concentration can be determined by dividing mass to volume which has been strictly controlled during sampling with fixed flow rate.
