The Series PMI Particulate Matter Transmitter is designed to measure indoor air quality by detecting particulate matter in an office environment or HVAC duct. Using laser scattering technology, the Series PMI can measure particles as small as 0.3 µm, making it an essential component of any indoor air quality monitoring system. The optional relay combined with the settable alarm and control parameters allow the Series PMI to be a stand-alone controller.
