This device is composed of aerosol generator, mixing system, flow reference and concentration calibration system. It uses the aerosol generation system to provide a quantitative supply of test particles, and uses uniform dilution, diffusion, stabilization, etc. to transport aerosols with a set concentration, and adopts aerosol photometer mass concentration standard device (reference photometer) or filter film to weigh Law as a traceability method.
