The Dust Sentry Pro is a real-time multi-channel particle monitor for aerosol profiling. It is designed for those who need to monitor and manage multiple outdoor dust and particle size fractions simultaneously and in real-time. The Dust Sentry Pro delivers simultaneous measurement of PM10, PM2.5, PM1, TSP, and particulate counts for 8 channels: 0.3, 0.5, 0.7, 1.0, 2.0, 3.0, 5.0, 10 microns. Packaged in a robust weather-proof, lockable enclosure, the Dust Sentry Pro is light enough for one-person site installations. Integrated solar shielding prevents the enclosure from overheating in climates with high solar irradiance.
