The air quality sensor on the AirLink can measure particulates as small as 0.3 microns with a concentration accuracy of +/- 10 micrograms per cubic meter.
The device can provide a reading of particulates from less than 1 micron (PM1) to less than 10 microns (PM10). Inhalable particulates that are 2.5 microns or smaller are small enough to penetrate deeply into your lungs and can cause difficulty breathing in some people.
You can choose from air quality indexes of 9 different countries including Canada, UK, US, Mexico, China, South Korea, EU, Australia, and India.
