The HAZ-DUST EPAM-7500 is a wireless PM portable monitor for real-time measurements of particulate matter, temperature, and relative humidity in ambient and indoor air. Interchangeable size-selective sampling heads allow PM10, PM2.5, PM1.0, respirable, or TSP monitoring. Configure with accessories needed for your application, including measuring wind speed and direction. A filter holder positioned directly behind the optical sensor provides concurrent gravimetric sampling for cross-calibration of optical sensor, further particulate speciation, and determination of metal and carbon content.
