TSI Dusttrak Environmental Monitor 8543

TSI Dusttrak Environmental Monitor 8543

Simultaneously measure PM1, PM2.5, Respirable, PM10, and total PM size fractions. DustTrak Environmental Monitor 8543 is a data-logging, light-scattering laser photometer that enables simultaneous real-time aerosol mass readings of particulate matter. DustTrak air monitors use a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. The DustTrak Environmental Monitor 8543 is on the South Coast AQMD pre-approved list of instruments for Rule 1466.

Key Features

  • Simultaneously measure aerosol concentrations corresponding to PM1, PM2.5, PM10 and total size fractions
  • STEL alarm set points
  • Automatic zeroing minimizes the effect of zero drift
  • Perform in-line gravimetric analysis for custom reference calibrations
  • Manual and programmable data logging functions
  • Aerosol concentration range 0 to 1000 ug/m³
  • Environmental protected and tamper-proof with Environmental DustTrak Enclosure
  • Cloud Data Management System for efficient remote monitoring
