Met One Instruments, Inc. AQ EAGLE system. It sounds like a useful tool for monitoring ambient air quality. The ES-405 Particulate Profiler appears to be a reliable and efficient instrument for measuring particulate mass concentrations in real-time for PM10, PM4, PM2.5, and PM1. The system’s portability, ease of use, and cost-effectiveness make it ideal for fugitive emissions and neighborhood-scale community monitoring projects.

The inclusion of the CCS COMET Cloud Plus+ modem, the AIO 2 Sonic Weather Sensor, and a 3-year cell data service plan, as well as two complimentary annual calibrations, is also impressive. The personalized access to a secure cloud web page, where averaged data is reported every 15 minutes domestically and every one hour internationally, is a great feature. The opt-in feature for data sharing for crowd-sourced research initiatives is also a welcome addition.

The example of real-time data reporting on a custom dashboard for the locally installed AQ EAGLE in Grants Pass, Oregon, USA, looks comprehensive and easy to read. The charts and graphs detailing PM concentrations in PM10, PM4, PM2.5, and PM1, as well as wind speed and direction, temperature, relative humidity, barometric pressure, and historical device data, are informative and useful for interpretation. Overall, the AQ EAGLE system appears to be a reliable and efficient tool for monitoring air quality.
