Aeroqual Dust Monitors

Dust Sentry integrated system banner2

Dust Sentry is a robust monitor with cutting edge software that makes outdoor dust monitoring easy:

  • Measures dust and particulate continuously
  • Real-time PM10, PM2.5, PM1 or TSP
  • Purpose designed for outdoors
  • Connect wind and noise sensors
  • Intuitive, user-friendly software
  • WIFI and cellular connectivity
  • SMS/email alerts, FTP, API
  • Battery/solar power compatible
  • Add gas measurements at any time



Dust Sentry is a purpose-build, robust, integrated and turnkey solution designed for optimal performance in rugged outdoor environments.

  • Purpose-designed enclosure rated IP65, with solar shielding armour and high reflective powder coating, to reduce the thermal impact on measurement and components.
  • Rugged instrument designed to operate in the toughest environments, operating range -10°C to +50°C.
  • Plug and play environmental parameters, such as wind and noise, are easily integrated – and the data is viewed on the same software platform.
  • Robust nephelometer and sharp cut cyclones for precise dust measurement, producing defensible data.
  • Integrated heated inlet as standard, to reduce humidity effects on particulate measurement.
  • Wireless and cellular data connectivity for remote access. WIFI instrument network capability.

Dust sentry purpose built outdoor monitoring



Industrial operators who need a cost-effective and robust solution to show particulate levels generated by site activities are within regulatory or permitted limits:

  • Construction and remediation
  • Industrial perimeter or fenceline monitoring
  • Quarry and mine operations
  • Port and bulk handling terminals
  • Waste management and landfill sites
  • Brownfield developments


Environmental consultants who require defensible particulate measurement for their clients’ air quality permits, EIA and Greenfield baseline studies, or who need to measure multi-channel PM size fractions.

Regulatory authorities who require deployable rapid response monitoring.

Environmental Health and Safety (EHS) managers who need to demonstrate that they are providing a safe work environment for people in their care.

Researchers who are on a limited budget and want to collect accurate, scientifically robust data.

who is Dust Sentry for


Dust Sentry

Dust Sentry combines a light scattering nephelometer and sharp cut cyclone to deliver defensible and accurate mass measurement of specific dust particles. It can be configured for PM10, PM2.5, PM1, or TSP.

Dust Sentry Pro

Dust Sentry Pro 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.

Upgradable to measure gaseous pollutants

Dust Sentry can also be upgraded to measure VOCs, Ozone and NO2. Find out more on the AQS page.

Meteorological and environmental parameters

All Dust Sentry products have the option to integrate environmental sensors for:

  • Temperature
  • Humidity
  • Noise
  • Barometric pressure
  • Precipitation
  • Solar radiation
  • Wind speed and direction
