Built on the same platform as the MFC PLUS controller, the VFC PLUS system accurately calculates and records the volumetric flow rate of the TSP, PM10 or PM2.5 high volume air sampler. The VFC PLUS controller use the ambient barometric pressure, ambient temperature and the pressure drop across the filter holder to accurately calculate the actual ambient volumetric flow rate.
