Aeroqual Dust Sentry PM10 Aeroqual

The Dust Sentry PM10 Dust Monitor is for:

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
• Quarry and mine operations
• Port and bulk handling terminals
• Waste management sites.

Environmental Consultants who require defensible particulate measurement for their clients’ air quality permits.

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.

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

What is it and what can it measure?
The Dust Sentry is a modular air quality monitoring instrument for the measurement and compliance of specific dust and particulate designation. It provides a real-time particulate measurement of PM10 using a well-proven near forwarding light scattering nephelometer and high precision sharp cut cyclone – with a measurement range of 0-60,000 μg/m3. By changing the sharp cut cyclone, the Dust Sentry can be configured to measure PM2.5, PM1 or TSP.

Dust Sentry can also be upgraded to measure VOCs, Ozone, and NO2.

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

Packaged in a robust weatherproof, 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 photodiode. The nephelometer has an on-board temperature sensor that corrects for thermal drift, sheath air filter to keep the optics clean and automatic baseline drift correction.

The sharp cut cyclone is a precision-engineered component fitted to the Dust Meter inlet that physically selects particles 10 microns in diameter and below. This ensures precise measurement of only the PM10 size fraction. 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.

Air monitoring software and communication
The instrument includes an embedded PC, up to 20 years of onboard data storage, and two powerful software systems. Aeroqual Connect is the instrument operating software. It opens in your browser so no software needs to be installed or updated. With Aeroqual Cloud you can remotely access data via a web browser on any device, even when your instrument is offline. Capabilities include:

• Wireless communications
• Integrated data platform
• Wind and pollution roses
• SMS and email alerts
• Access through an API
