Air Quality and Environmental Monitor
Indoor Air Quality Monitors
Models 7301-AQM1 and
7301-AQM2
(CO2, Temp, RH, and TVOC)
The Particles Plus® 7301-AQM1 and 7301-AQM2 Remote Particle Counters measure particles from 0.3 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM). These user-friendly instruments display up to six particle size channels, temperature, relative humidity, and CO2 (AQM1) or CO2 + TVOC (AQM2).
Designed for research, industrial hygiene, indoor air quality, and cleanroom applications, the 7000 Series offers exceptional versatility. From the cleanest labs to the dirtiest worksites, confidently monitor any environment thanks to the industry’s highest particle concentration limits.
With 10 hours of continuous battery operation and up to 100 hours using our patented intelligent battery management system, these instruments are built for long-lasting performance on a single charge. The Particles Plus® Real-Time Monitoring technology enables dynamic particle investigations, displaying data in particles per second to help users quickly locate contamination sources in controlled environments.
Data can be managed directly on the device or through the free Particles Plus® software. Export raw data in .CSV format or generate compliant reports (ISO 14644-1, EU GMP Annex 1, or FS 209E). Remote diagnostics are also available from anywhere with an internet connection. The 7000 Series can function as a fully portable, battery-operated solution or be easily integrated into building automation and cleanroom management systems with multiple communication options.
