MicroVolume - Model 1100 - Low Volume Air Sampler
From Particulate Monitoring - Portable Air Sampling Equipment
The MicroVol 1100 low volume air sampler provides a flexible sampling platform for PM10, PM25 or TSP particulates and basic meteorological parameters. The MicroVol 1100 is suitable for both indoor and outdoor applications. The unit is microprocessor controlled and uses a mass flow sensor in conjunction with ambient temperature and pressure sensors to automatically maintain a constant volumetric flow rate.
