Aeroqual Dust Sentry PCX

The Dust Sentry PCX is the ultimate solution for simultaneous real-time measurement of PM1, PM2.5, PM4, PM10, and TSP. Producing accurate and defensible data, that can be accessed from anywhere, the Dust Sentry PCX is designed for those who need to monitor and manage multiple particulate size fractions for regulatory compliance applications. SCAQMD pre-approved, it’s suitable for use on a range of projects including construction, demolition, remediation, air quality research, and roadside monitoring.

  • Delivers simultaneous multi-channel measurement of PM1, PM2.5, PM4, PM10, TSP.
  • Benefit from efficient remote management with two-way communication, integrated flow measurement and control, and automated SMS and email alerts.
  • Robust, weather-proof enclosure, suitable for use in most conditions


The Dust Sentry PCX is a real-time multi-channel particle counter, that uses scattered light to size and count particles, assigning them to one of six particle count channels based on diameter. Using a proprietary algorithm, particle counts for each size fraction are converted into mass measurements.

Packaged in a robust, weather-proof, lockable enclosure, the Dust Sentry PCX is light enough for one-person site installations. The instrument includes an embedded PC, with more than 5 years data of on-board data storage and can be connected to Aeroqual’s Cloud air quality monitoring software platform.

What can it measure?

The Dust Sentry PCX provides continuous and simultaneous measurement of PM1, PM2.5, PM4, PM10, and TSP.

Options to integrate environmental sensors such as wind, noise, weather, and solar radiation make this a complete air monitoring solution for your next project.

Who is it for?

Used by various professionals, including industrial operators, environmental consultants, regulatory authorities, Environmental Health and Safety (EHS) managers, and researchers. The Dust Sentry PCX is a cost effective and robust solution to help identify if particulate levels resulting from site activities comply with regulatory or permitted limits, and to minimise the risk posed by fugitive dust to nearby sensitive receptors, workers, and the surrounding community.

Practical applications for the Dust Sentry PCX include:

  • Measurement of multi-channel fraction sizes
  • Construction activities and equipment emissions
  • EIA and Greenfield baseline studies
  • Air quality research
  • Roadside monitoring
