Indoor Air Quality Monitors

Designed for gas and particle pollutant measurements to better understand atmospheric chemistry and environmental public health, these internet enabled instruments provide a near-instantaneous look at changing pollutant concentrations, with peripheral sensors for measurement of environmental and meteorological parameters.

Models 5301-AQM and 5302-AQM

(CO2, Temp, RH, and TVOC)

The 5301-AQM and 5302-AQM Remote Air Quality Monitor measures and displays particle mass concentrations for PM1, PM2.5, PM5 and PM10 including temperature, relative humidity, CO2 (and TVOC in the 5302-AQM). This wall- mounted instrument is the most versatile remote air quality monitor available for fixed installations. The advanced power management and the industry’s first sleep mode, allows for long intervals between samples over extended and unattended operations. The AQM Series can easily integrate into a building automation and facility monitoring system via Ethernet, USB or (optional) Wireless 802.11 b/g, RS485 or RS232.

The 5301-AQM and 5302-AQM reports and displays 6 user-selectable particle size channels, as well as Carbon Dioxide (CO2), temperature, and relative humidity. The instrument monitors PM1, PM 2.5, PM5, PM 10 (and any other PM size value the user specifies) with an easy-to-use Channel Management control panel. The instrument also monitors flow, sensor status, date of last calibration, serial number, laser on-time, and date of manufacture for easy maintenance and warranty management. The remote monitor operates using a long-life internal 0.1 CFM pump.

View data and generate environmental reports real-time on screen, via printer or USB key, through the versatile output options, or export to the Instrument Management Software during monitoring system or network failure. The units can be controlled and monitored remotely via web browser from any PC, tablet or smartphone supporting up to 20 concurrent user sessions.

The 5301-AQM and 5302-AQM particle counter stores 45,000 time-stamped particle count and environmental data records for redundant protection in the event of a monitoring system or network failure. The AQM Series mass concentration mode approximates density in μg/m³ and PM (particle matter) allowing for density and refractive index corrections to ensure accuracy. The units meet ISO 21501-4 and JIS B9921. These instruments ensure compliance with an on-board pulse height analyzer.
