  • 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 color 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
