AIR QUALITY MONITOR Leading the industry in real-time dust monitoring, DustTrak™ DRX Aerosol Monitors can simultaneously measure both mass and size fraction. DustTrak DRX monitors are multi-channel, battery-operated, data-logging, light-scattering laser photometers that give you real-time aerosol mass readings and collects a gravimetric sample. They use a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. The DustTrak DRX Model 8533EP is outfitted with an external pump module that is designed to handle the rigors of continuous 24/7/365 monitoring applications such as construction sites, fugitive emissions monitoring at environmental sites, and other outdoor applications.
