Models 5301-AQM1 and 5301-AQM2

The Particles Plus® 5301-AQM1 and 5301-AQM2 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 5301-AQM2). This wall-mounted instrument is the most versatile remote air quality monitor available for fixed installations. Advanced power management and the industry's first sleep mode allow for long intervals between samples during extended, unattended operations. The AQM series 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.

The 5301-AQM1 and 5301-AQM2 report and display 6 user-selectable particle size channels, as well as carbon dioxide (CO2), temperature, and relative humidity. The instrument monitors PM1, PM2.5, PM5, PM10 (and any other user-specified PM size value) with an easy-to-use Channel Management control panel. The instrument also monitors flow, sensor status, last calibration data, serial number, laser on-time, and manufacturing data for easy maintenance and warranty management. The remote monitor operates using a long-life internal 0.1 CFM pump.

View data and generate real-time environmental reports on screen, via printer or USB stick, through the versatile output options, or export them to Particles Plus® instrument management software during system monitoring or in the event of a network failure. Particles Plus® instruments can be remotely controlled and monitored via web browser from any PC, tablet, or smartphone supporting up to 20 simultaneous user sessions.

The 5301-AQM1 and 5301-AQM2 particle counter stores 45,000 time-stamped particle counts and environmental data records for redundant protection in case of monitoring system or network failure. The AQM series mass concentration mode approximates density in µg/m³ and PM (particles), allowing for density and refractive index corrections to ensure accuracy. All Particles Plus® counters meet ISO 21501-4 and JIS B9921 standards. These instruments ensure compliance with an integrated pulse height analyzer.
