β Attenuation MethodPM10/2.5 Automated Dichotomous MonitorModel SPM-613D

  • SPM continuous particulate analyzer developed by joint patent with Japan Science and Technology department of government, Kimoto and Tisch Environmental

  • Black Carbon feature originated from work of DRI/EPA and measurement of OC/EC


Features

  • 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 = PMC

  • Use 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 sensitivity

  • Sample spots on fluorocarbon membrane filter useful for analyses of ion components and metal components after mass and Carbon direct measurement


Structure of SPM-613D


Virtual Impactor PM10 and PM2.5 Simultaneously


Validation and Calibration Device for Particle Size-Cut Testing

Particle generator and aerosol mixing chamber to test inlet separators and virtual impactors for size-cut and penetration curves
