Aranet4 Air Quality Monitor

CO₂ is a key indicator for fresh air. High concentrations of CO₂ can cause tiredness, headaches and dizzines. 

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).
