The Dust Sentry TSP 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 gives continuous real-time data on total suspended particulate matter (TSP) using a well proven near forward light scattering nephelometer – with a measurement range of 0-60,000 μg/m3. It is a flexible instrument that can be configured for many different applications. By adding a sharp cut cyclone, the Dust Sentry can be quickly and easily upgraded to measure PM10, PM2.5 or PM1. For simultaneous measurement of PM2.5, PM10, PM1 and TSP see the Dust Sentry Pro.

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 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 photodiode. 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.

Air monitoring software and communication

The instrument includes an embedded PC, up to 20 years of on board data storage, and a powerful air quality monitoring software. 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
