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.
