By identifying particulate matter in an office setting or HVAC duct, the Series PMI, Model PMI-2.5DC-N-N Particulate Matter Transmitter is intended to measure indoor air quality. The Series PMI, which measures particles as fine as 0.3 µm using laser scattering technology, is a crucial aspect of any indoor air quality monitoring system. The Series PMI may function as a stand-alone controller thanks to the optional relay, settable alarm, and control settings.
