The new DustTrak™ II Aerosol Monitor is a desktop battery-operated, data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings. It uses a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance.

It is suitable for clean office settings as well as harsh industrial workplaces, construction and environmental sites, and other outdoor applications. The DustTrak II Aerosol Monitor measures aerosol contaminants such as dust, smoke, fumes, and mists.

  • Measure aerosol concentrations corresponding to PM1, PM2.5, PM10 or Respirable size fractions
  • STEL alarm setpoint
  • Automatic zeroing (with optional zero module) minimizes the effect of zero drift
  • Perform in-line gravimetric analysis for custom reference calibrations
  • Manual and programmable data logging functions
  • Desktop Unit
  • Aerosol Concentration range 0.001 to 150 mg/m3
