TSI AM520 SidePak Personal Aerosol Monitor

The SidePak Personal Aerosol Monitor AM520 is a small, single-channel, portable, battery-operated, data-logging, light-scattering laser photometer that provides real-time aerosol mass concentration readings of dusts, fumes, mists, smoke, and fog within a worker breathing zone. Newly designed inlet conditioners increase the mass concentration capability and provide size fraction cut points for PM10, PM4 (Respirable), PM5 (China Respirable), PM2.5, PM1, and 0.8 μm Diesel Particulate Matter (DPM). This monitor is the perfect solution for real-time, personal aerosol sampling in a variety of workplace environments, including general industry, foundries, construction sites, chemical plants, refineries, petrochemical, power and utilities, transportation, aerospace, maritime, confined spaces and mining.
