A multi-channel, battery-operated, data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings. The TSI 8534 DustTrak DRX Aerosol Monitor can simultaneously measure mass and size fractions. 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.

Suitable for clean office settings and harsh industrial workplaces, construction and environmental sites, and other outdoor applications.

A handheld monitor measures aerosol contaminants such as dust, smoke, fumes and mists.
