Davis AirLink Air Quality Monitor

AirLink Air Quality Monitor

An air quality monitor can help users take steps to deal with poor air quality, especially for those who are particularly sensitive. The AirLink® Professional Air Quality Monitor can be used inside the home or outdoors. An AirLink Quality Monitor provides real-time Air Quality Index readings and sends them to a phone or computer.

The air quality sensor measures particulates (PM) in the air by size: PM1, PM2.5, and PM10. The air quality meter gives users information both as data and as a color-coded graph that is easy to understand. AirLink is one of the best air monitors on the market for home and outdoor air quality concerns.



Measures particulates as small as 0.3 micrometers with an accuracy of +/-10 micrograms per cubic meter in concentrations.
