Indoor Air Quality Monitors

8301 02 AQM

Models 8300-AQM1 and 8300-AQM2 

(CO2, Temp, RH, and TVOC)

The Particles Plus® 8300-AQM1 and 8300-AQM2 Series Handheld 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 8300-AQM2. This instrument is the most versatile handheld 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 8300-AQM2 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 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.

User friendly field calibration for the integrated environmental sensors allows for single or dual point offsets, and ensures accuracy for air quality investigations. View data and generate environmental reports real-time on screen, via printer or USB key, or export to Particles Plus® Instrument Management Software. Particles Plus® instruments can be controlled and monitored remotely via web browser from any PC, tablet or smartphone supporting 20 concurrent user sessions.

The 8300-AQM1 and 8300-AQM2 store up to 45,000 time stamped particle count and environmental 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. All Particles Plus® counters meet ISO 21501-4 and JIS B9921. The 8300-AQM1 and 8300-AQM2 ensure compliance and accuracy with an on-board pulse height analyzer.
