Models 7300-AQM1 e 7300-AQM2

The Particles Plus® 7300-AQM1 and 7300-AQM2 series remote particle counter and environmental monitor measures particles from 0.3 to 25 µm with mass concentration and stores indoor air quality measurements of temperature, relative humidity, CO2 (and TVOC in the 7300-AQM2). This instrument is the most versatile remote air monitor available, with advanced power management and the industry's first sleep mode, allowing battery operation for periods that can exceed one month on a single charge. The AQM series can be used as a standalone battery-powered instrument or 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 report and display 6 user-selectable particle size channels, as well as carbon dioxide (CO2), temperature, and relative humidity. The 7300-AQM2 model includes a PID sensor for TVOC. The instrument monitors PM1, PM 2.5, PM5, PM 10 and TPM (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 date, serial number, laser on time, and manufacturing date for easy maintenance and warranty management.

Intuitive field calibration for integrated environmental sensors allows single or dual point offsets and ensures accuracy for air quality investigations. View data and generate real-time environmental reports on screen, via printer or USB stick, or export them to Particles Plus® instrument management software. Particles Plus® instruments can be remotely controlled and monitored via web browser from any PC, tablet, or smartphone supporting 20 simultaneous user sessions.

The 7300-AQM1 and 7300-AQM2 store up to 45,000 timestamped particle counts and environmental data records, providing data redundancy on each instrument. The AQM's mass concentration mode approximates density in µg/m³ and allows density and refractive index corrections to ensure accuracy. All Particles Plus® counters meet ISO 21501-4 and JIS B9921 standards. The 7300-AQM1 and 7300-AQM2 ensure compliance and accuracy with an integrated pulse height analyzer.
