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.
The DustTrak™ Environmental Monitor 8540 is designed for harsh outdoor settings, as well as harsh industrial workplaces, construction and environmental sites, and other outdoor applications. The robust design has an enhanced optics module, built-in auto-zero capability, and a longer life pump (>10,000 hours) which is field replaceable. The photometer measures aerosol contaminants such as dust, smoke, fumes and mists in environments from -4 to 122°F.
