DustTrak® II Aerosol Monitor Model 8530

Desktop or Handheld Units for Any Environment, AnyApplication

The new DUSTTRAK II Aerosol Monitors are battery-operated,data-logging, light-scattering laser photometers that give youreal-time aerosol mass readings. They use a sheath air system thatisolates the aerosol in the optics chamber to keep the optics cleanfor improved reliability and low maintenance. Suitable for cleanoffice settings as well as harsh industrial workplaces,construction and environmental sites and other outdoorapplications. DUSTTRAK II monitors measure aerosol contaminantssuch as dust, smoke, fumes and mists.
