HAZ-DUST EPAM-7500
Portable Direct-reading PM Monitor and Air Station
The HAZ-DUST EPAM-7500 portable monitor and air station provides simultaneous 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. Optional accessory for measuring ultrasonic wind speed and direction is available. 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.
- Two sampling techniques for ambient and indoor particulate matter measurement
- Sensitive IR optical light scattering for real-time measurement and graphical representation of PM profile
- 47-mm FRM-style filter holder for concurrent gravimetric sampling for cross-calibration and further PM speciation
