FeaturesFeatures
Ambient PM2.5 fraction is emphasis of medical, epidemiological researchers Ambient PM10 or PM2.5 and optical black carbon can be measured simultaneously on a continuous basis. PM Coarse is calculated and reported as PM10 - PM2.5 = PMCUse of virtual impactor uses two measurements of fine and coarse particles simultaneouslyMonitor’s fluorocarbon membrane filter reduces gas, moisture effect to minimum, assures high sensitivitySample spots on fluorocarbon membrane filter are useful for analyzing ion components and metal components after mass and Carbon direct measurements
