TSI Dusttrak Environmental Monitor 8540

TSI Dusttrak Environmental Monitor 8540

Measure PM1, PM2.5, Respirable, PM10, or total PM size fractions. DustTrak Environmental Monitor 8540 is a 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. DustTrak Environmental Monitor 8540 is on the South Coast AQMD pre-approved list of instruments for Rule 1466.

Key Features

  • Measure aerosol concentrations corresponding to PM1, PM2.5, or PM10 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 0.001 to 400 mg/m³
  • Environmental protected and tamper-proof with Environmental DustTrak Enclosure
  • Cloud Data Management System for efficient remote monitoring
  • Heated Inlet Sample Conditioner to reduce humidity effects
  • On the South Coast AQMD pre-approved list of instruments for Rule 1466
