Carbon dioxide (CO2) is a naturally occurring gas; recommended indoor concentration is 400-1000 ppm.
Exceeding this level can cause fatigue and reduced concentration, while levels above 2000 ppm lead to more severe symptoms such as headaches and dizziness.
LCD display with a 1.7" (4.3 cm) diagonal shows CO2 values and levels.
Displays current value or average CO2 concentration over 1 h / 8 h / 24 h.
