Aeroqual Dust Sentry Pro Dust Particle Counter

The Dust Sentry Pro provides simultaneous real-time measurement of PM10, PM2.5, PM1, and TSP, producing accurate, defensible data, accessible anywhere. Designed for those who need to monitor and manage multiple outdoor dust and particle size fractions. Suitable for use on a range of projects, including construction and remediation activities, air quality research, and roadside monitoring.


 The Dust Sentry Pro is a real-time multi-channel particle monitor. For aerosol profiling, measuring, and reporting real-time data in 1-minute intervals. The Dust Sentry Pro comprises an optical particle counter that converts counts to a mass fraction via a proprietary algorithm stored in the system firmware.

The particle counter uses scattered light to measure and count particles within the aerosol sample flow, assigning them on the basis of size to one of eight particle channels.

Packaged in a robust weather-proof, lockable enclosure, the Dust Sentry Pro is light enough for one-person site installations. The instrument includes an embedded PC, up to 20 years of on-board data storage, and a powerful air quality monitoring software.

What can it measure?

The Instrument delivers simultaneous measurement of PM10, PM2.5, PM1, TSP, and particulate counts for 8 channels: 0.3, 0.5, 0.7, 1.0, 2.0, 3.0, 5.0, 10 microns. For specific dust and particulate emissions, see the Dust Sentry PM10Dust Sentry PM2.5 or Dust Sentry TSP.
