Aerotrac II Particle  Size Analyzer

Aerotrac II Particle Size Analyzer

Microtrac MRB | Particle Size Analysis

The Aerotrac II is an analyzer for Particle size distributions & concentration ratio analysis (calculated from transmitted laser light) for suspended particulates in air such as atomized droplets, powders, spray particles, mist, etc.


  • Wide range of applications
  • Measurement modes to support various applications
  • Key start (manual operation via keyboard)
  • Auto start (automatically starts when detecting scattered light from particulates)
  • Measurement start via external signal input
  • 0.02msec~ Accurate particulate analysis at short measurement intervals
  • Provided with multiple scattering correction software as standard
  • The instrument can be set up in a limited space
  • Equipped with a semiconductor laser
