The SidePak AM520i Personal Aerosol Monitor is a small, single-channel, portable, battery-operated, data-logging, light-scattering laser photometer that provides real-time aerosol mass concentration readings of dust, 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 various potentially volatile environments.

​Features and Benefits

  • Dual display and data logging of mass concentration and response concentration on one screen (i.e. for respirable silica, welding fume and DPM monitoring applications)
  • Stores up to 10 custom calibration factors on the instrument for different applications
  • CSA Certifications for North America
  • Audible and visual alarms
  • 0.8 μm DPM impactor
  • PM5 China respirable size fraction impactor
  • Real-time mass concentration measurement and data logging for “in-the-field” data analysis
  • Push button menu operation or programmable through newly improved TrakPro v5 Software
  • User-selectable alarm levels to alert workers to high aerosol concentrations
  • Robust impactors enable reliable size fraction measurements at higher aerosol concentrations over longer run times
