Real-time dust monitoring takes a giant leap forward! Only the DustTrak™ DRX Aerosol Monitor 8534 can simultaneously measure both mass and size fraction - no other monitor can do both. The DustTrak DRX handheld monitor is a battery operated, data-logging, light-scattering laser photometers 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.
It is suitable for clean office settings as well as harsh industrial workplaces, construction and environmental sites and other outdoor applications. The DustTrak DRX handheld monitor measures aerosol contaminants such as dust, smoke, fumes and mists."
