The TSI 8533EP DustTrak DRX is equipped with an external pump module designed to handle the rigours of continuous 24 hours a day, seven days a week monitoring applications such as construction sites, fugitive emissions monitoring at environmental sites and other outdoor applications.

A multi-channel, battery-operated, data-logging, light-scattering laser photometer provides real-time aerosol mass readings and collects a gravimetric sample. Simultaneously measures both mass and size fraction. 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.

Features & Benefits

  • Energy-efficient, long-lasting external pump for continuous, unattended, 24/7, outdoor monitoring applications
  • Simultaneously measure size-segregated mass fraction concentrations corresponding to PM1, PM2.5, respirable, PM10 and PM Total size fractions
  • STEL alarm setpoint
  • 5.7-inch touchscreen interface
  • Trakpro data analysis software
  • Automatic zeroing (with optional zero module) minimises the effect of zero drift
  • Perform in-line gravimetric sampling for custom reference calibrations
  • Manual and programmable data logging functions
  • Aerosol concentration range 0.001 to 150 mg/m3
  • Environmental protected and tamper-proof with Environmental Enclosure


  • Outdoor environmental monitoring
  • Baseline trending and screening
  • Engineering control evaluations
  • Remote monitoring
  • Process monitoring
  • Emissions monitoring
