The Aranet4 device is calibrated at the factory. However, the user can perform CO2 calibration manually when needed. During the manual calibration, the Aranet4 device must be exposed to fresh air (about 400 ppm of CO2) and the environment should be stable (not changing). Maintain a distance of at least 1 meter from the device during the calibration process. Perform this calibration outdoors on an annual basis.

Aranet4 takes CO2 monitoring to the next level of portability, usability, and utility.
Understand your risk. Take it everywhere: home, school, gym, office, transit, air travel.
The lower the CO2, the less risk of exposure to rebreathed air.
Aranet4 shows CO₂ measurements directly on its e-ink screen with a corresponding colour indicator and configurable sound alarms.
Aranet4 uses the most precise Nondispersive infrared (NDIR) sensor technology for accurate CO₂ measurements. It has a super-efficient e-ink display that extends its battery life up to 2 years (2xAA).
Aranet4 device is Bluetooth compatible, using your iOS or Android device.

Outdoor air is ~420 ppm CO2. Unoccupied indoor spaces may be higher due to combustion sources such as gas appliances, candles and fireplaces.
For occupied spaces, each increase of 400ppm above unoccupied = 1% rebreathed air.
Cognitive function impairment increases above 1000ppm and is pronounced over 1400 ppm.1
