The Particles Plus 7301-AQM2 Air Quality Monitor measures particles from 0.3 μm to 25.0 μm and has a mass concentration mode that approximates density in μg/m³. The unit displays simultaneous PM1, PM2.5, PM5, PM10 and TPM data, while monitoring CO2, TVOC, Temperature, Humidity and Barometric Pressure. With an internal 0.1 CFM (2.83 LPM) vacuum pump, the 7301-AQM2 can be used as a stand-alone battery-operated instrument or be easily integrated into a building management system via Ethernet or (optional) Wireless 802.11 b/g. Particles Plus counters can be controlled and monitored remotely via web browser. The 7301-AQM2’s mass concentration mode allows for density correction and refractivity index input for up to 6 particle size channels.
