Accurate and affordable real-time outdoor particulate monitoring.
The Dust Sentry provides real time, continuous particle measurement of TSP, PM10, PM2.5 or PM1 with datalogging and alarm relay outputs. Numerous integrated options including SMS and/or email notifications, weather sensors, noise and mounting equipment make the Dust Sentry a flexible base system suitable for a wide range of applications.
Compared to reference-equivalent monitors like TEOMs and BAMs which lack sensitivity at short sampling periods, the Dust Sentry reports accurately at 1 minute intervals and has a much lower total cost of ownership (up to 5x less). In addition, the Dust Sentry is compact, re-locatable and can integrate wind and weather sensors for maximum utility.
