It is a perfect device to monitor the air quality in your home, office, greenhouse or other indoor premises

Carbon dioxide CO2 is a non-toxic gas but the rising of CO2 concentration in air will have potential impact on the radiation balance of atmosphere, known as ‘greenhouse’ effect. Hence the level of CO2 should be monitored on regular basis.
