- Model MicroVol 1100 - Low Volume Air Sampler

From

The MicroVol 1100 low volume air sampler provides a flexible sampling platform for PM10, PM2.5 or TSP particulates and basic meteorological parameters.

The MicroVol 1100 is designed for monitoring both indoor air quality as well as outdoor. The MicroVol 1100 is a low power, low noise instrument that can sample particulates in residential or workplaces whilst using minimal power and causing minimal distraction.

The MicroVol 1100 uses active volumetric flow control that maintains a constant flow rate (3LPM), ensuring accurate measurement of particulates no matter the particulate loading.
