TSI AM520i SidePak Personal Aerosol Monitor

The SidePak Personal Aerosol Monitor AM520i 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).

The SidePak AM520i has IECEx, ATEX, CSA and IECEx-SIM certifications, meaning it can help you protect workers and maintain compliance in a variety of potentially volatile environments.
