Aerodynamic particle sizer TSI-APS 3321

spektrometr-perex.jpeg The aerodynamic particle sizer TSI 3321 is a device for accurate measurement of aerodynamic diameter of aerosol particles. It is a compact and portable general purpose apparatus applicable to measurement of aerosol particle size under laboratory and field operating conditions. The aerodynamic diameter measurement is based on a sophisticated 'time-of-flight' technique. It is a size characteristics of a particle that determines the particle motion behaviour when suspended in the air. The sizer measures simultaneously the aerodynamic diameter and the equivalent diameter, the latter based on scattered light intensity.
