7300-AQM1 and 7300-AQM2 Remote
Air Quality and Environmental Monitor
Indoor Air Quality Monitors
Models 7300-AQM1 and
7300-AQM2
(PM, CO2, Temperature, RH, and TVOC)
The Particles Plus® 7300-AQM1 and 7300-AQM2 Remote Particle Counters measure particles from 0.3 to 25.0 μm at a flow rate of 1.2 LPM. These user-friendly instruments display up to six particle size channels, temperature, relative humidity, and CO2 (AQM1) or CO2 + TVOC (AQM2).
Designed for cleanroom monitoring, indoor air quality, industrial hygiene, research, and health & safety applications, the 7300-AQM Counters offer exceptional versatility. From the cleanest labs to the dirtiest worksites, confidently monitor any environment with the industry’s highest available 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 included Particles Plus® IMS 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 7300-AQM Series can function as a fully portable, battery-operated solution or be easily integrated into building automation
