The Dust Sentry PM10 Dust Monitor is an affordable, portable device which utilizes a light scattering nephelometer and a precision-engineered sharp cut cyclone to provide robust, accurate measurements. It is used by environmental consultants, EHS managers, regulatory authorities and researchers who need to:
  • Measure particle levels to ensure that pollutants generated by construction activities are within regulatory or permitted limits
  • Provide defensible particulate measurements for their clients to obtain air quality permits
  • Demonstrate that the work environment is safe
  • Provide speedy, reliable incident monitoring
  • Cost-effectively gather strong, accurate data

This modular air quality monitoring instrument is designated for real-time measurement of PM10 dust and particulate matter ranging from 0-60,000 μg/m3. It can also be configured to measure PM2.5, PM1 or TSP. In addition, upgrades, which enable the device to measure VOCs, Ozone and NO2, are available, and you can choose to integrate environmental sensors (i.e. wind, noise, weather, solar radiation) to make this an end-to-end air quality monitoring solution. Added benefits include integrated solar shields which prevent overheating as well as a weather-proof, secure enclosure.

This modular instrument provides continuous, real-time measurement of airborne particles by calculating particulate mass with a light scattering nephelometer that features a visible laser diode and a high precision sharp cut cyclone which chooses particles with diameters of 10 microns or less and employs a heater to lessen moisture when the humidity is elevated.

Utilizing Areoqual’s integrated software, Aeroqual Connect and Aeroqual Cloud, the Dust Sentry can store up to 20 years of data which can be remotely/wirelessly accessed through an API even when the device is disconnected – all without ever installing or updating software. The system provides wind and pollution roses to aid in analysis as well as SMS and email notifications for real-time monitoring.
  • Packaged in a robust weather-proof, lockable enclosure, the Dust Sentry is light enough for one-person site installations. Integrated solar shielding prevents the enclosure from overheating in climates with high solar irradiance. Smart technology.
  • A nephelometer is an optical sensor that uses light scattering from particulate matter to provide a continuous real-time measurement of airborne particle mass. The light source is a visible laser diode and scattered light is measured in the near forward angle using focusing optics and a photo diode. The nephelometer has an on-board temperature sensor which corrects for thermal drift, sheath air filter to keep the optics clean and automatic baseline drift correction.
  • The inlet is fitted with a heater that is used to remove moisture from the incoming sample. Moisture can reduce the accuracy of optical measurement, so for best results the inlet heater is activated in the event of high humidity.
