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
