Dilution system for particle analyzer

摘要: An airborne particle analyzer is provided with an adapter which affords dilution of the aerosol sample introduced into analyzer. The receives clean exhaust air, would otherwise be discharged ambient, and directs air to injector through directed sensing area has adjustable permit discharge ambient a measured portion so that corresponding volume new drawn unit. injected center continuously circulating in unit directly at area. Regulation amount fluid provides control over for entrainment and, correspondingly, degree sample.
