只有最新型的 DustTrak™ DRX 气溶胶监测仪可以 同时测量质量浓度和粒径尺寸，其他的监测仪都没有这项功能。 DustTrak DRX 气溶胶检测仪是由电池驱动，内部配有数据记录系统和光散射激光光度计，抽气泵，可供气溶胶数值的实时观测。 它使用鞘气系统使得光学元件室中的气溶胶分隔，光学元件能够保持清洁，提高了设备的可靠性，降低了维修率。
DustTrak DRX 8533EP 外部配有抽气泵模块，专门用来处理连续24小时/7天/365天的全天候监测应用，包括建筑工地和户外场所的监测，以及环境中难以捕捉的排放物的监测。 

DUSTTRAK DRX 监测仪可以检测气溶胶污染物，如灰尘、烟雾、烟尘和雾气等 。
