Models 5300-AQM1 and 5300-AQM2
(CO2, Temp, RH, and TVOC)
The Particles Plus® 5300-AQM1 and 5300-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 research, industrial hygiene, indoor air quality, and cleanroom applications, the 5000 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.
One of the key advantages of the 5000 Series as a remote particle counter is its built-in touchscreen display. It provides real-time visual feedback for technicians working in critical areas, enabling immediate identification of elevated particle counts. Adjustable audible alarms offer an additional layer of awareness in critical 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 5000 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.
