Our Dust Sentry PM10 Dust Monitor can be configured for many different applications: construction, waste, mining, transportation, consultancy and research. The instrument is designed to provide reliable real time indicative particulate measurement of PM10 using a well proven near forward light scattering nephelometer and high precision sharp cut cyclone. By changing the sharp cut cyclone the Dust Sentry can also measure PM2.5, PM1 or TSP. For simultaneous measurement see the Dust Profiler.

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, automatic baseline drift correction and a fibre optic span system to provide a check of the optical components.

The sharp cut cyclone is a precision engineered component fitted to the Dust Meter inlet that physically selects particles 10 microns 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.

The instrument includes an embedded PC, with over 20 years of on board data storage, and two powerful software systems as standard. 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 on any device even when your instrument is offline. There are also several options available including: wireless communications, SMS and email notifications and weather sensors. The instrument is packaged in a robust, lockable enclosure and is light enough for one person site installations. Solar shields prevent the enclosure from overheating in climates with high solar irradiance.
