Models 7301-AQM and 7302-AQM (PM, CO2, Temp, RH, and TVOC)
The Particles Plus 7301-AQM and 7302-AQM Series Remote Particle Counter and Environmental Monitor measures 0.3 to 25 µm particles with mass concentration and stores indoor air quality measurements of temperature, relative humidity, CO2, and TVOC in the 7302-AQM. This instrument is the most versatile remote Air Monitor available, with advanced power management and the industry’s first sleep mode, allowing for battery operation of periods that can exceed a month on a single charge. The AQM Series can be used as a stand-alone battery operated instrument or it can be easily integrated into a building automation and facility monitoring system via Ethernet, USB or (optional) Wireless 802.11 b/g, RS485 or RS232 connection.
The AQMs reports and displays 6 user-selectable particle size channels, as well as carbon dioxide (CO2), temperature, and relative humidity. The model 7302-AQM includes a PID Sensor for TVOC. The instrument monitors PM1, PM 2.5, PM5, PM 10 & TPM (and any other PM size value the user specifies) with an easy-to-use Channel Management control panel.
The 7301-AQM and 7302-AQM store up to 45,000 time stamped particle count and environ-mental data records which provides data redundancy on every instrument. The AQMs mass concentration mode approximates density in µg/m³ and allows for density and refractive index corrections to ensure accuracy.
