7302-AQM air quality monitor (particulate matter, CO2, temp, RH and TVOC)
The Particle Plus AQM series external particle counter and environmental monitor measures 0.3 μm to 25 μm particles with mass concentration. Additionally, the 7302-AQM measures particulate matter, temperature, relative humidity, CO2 and volatile organic c
The Particles Plus 7302 external particle counter AQM offers cleanroom technology professionals an extremely accurate solution for monitoring air quality and process conditions in controlled environments. This advanced measuring instrument reports simultaneously on six user-selectable channels and also measures carbon dioxide (CO2), temperature and relative humidity. Thanks to the integrated PID sensor, the 7302 model also detects volatile organic compounds, which is essential for critical air quality surveys and ventilation tests according to ASHRAE 62.
Advanced monitoring and data management
This particle counter monitors PM1, PM 2.5, PM5, PM 10 and TPM with precision that meets ISO 21501-4 and JIS B9921 standards. Users can rely on reliable operation due to the long-life laser diode technology and an internal vacuum pump with automatic flow control. The system stores up to 45,000 records with time stamp, which can be easily exported via USB, Ethernet or optional wireless connections. For optimal maintenance convenience, the device independently checks the sensor status, the last calibration date and the laser run time.| Particle size range | 0.3 to 25.0 μm |
