Leading the industry in real-time dust monitoring, the DustTrak™ DRX Aerosol Monitor 8533 can simultaneously measure both mass and size fraction. The DustTrak DRX desktop monitor is a multi-channel, battery-operated, data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings and collects a gravimetric sample. 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.
It it is suitable for clean office settings as well as harsh industrial workplaces, construction and environmental sites, and other outdoor applications. The DustTrak DRX monitor measures aerosol contaminants such as dust, smoke, fumes and mists.
