FeaturesFeatures

Ambient PM2.5, or fine fraction is what medical and epidemiological researcher are concerned about for health effects Ambient PM10, PM2.5 and Optical Black Carbon can be measured simultaneously on continuous basis. PM Coarse is calculated and reported as PM10 - PM2.5 = PMCUse of virtual impactor enables two measurements of both Fine and Coarse particles simultaneously with a Japan patented system*Monitor uses proprietary fluorocarbon membrane filter which reduces gas and moisture effect to minimum, and assures high sensitivitySample spots on fluorocarbon membrane filter useful for analyses of ion components and metal components after mass and Carbon direct measurement
