Common fields 
1. Carbon dioxide monitoring of various industrial and agricultural plants, workshops, greenhouses, clean rooms,
etc. 
2. Ventilation control and environmental quality monitoring required for homes, villas, office buildings, meeting rooms,
classrooms and other fields. 
3. Ventilation control and environmental quality monitoring in public places such as hotels, exhibition halls, hospitals, shopping
malls, bars, restaurants, airports, train stations, entertainment halls, and theaters. 
4.Units that produce and use carbon dioxide gas, etc. 
Non-mandatory reference rating: 
a) 350 ~ 400ppm-usual outdoor air level. 
b) 400 ~ 1,000ppm-typical value in well-ventilated living space. 
c) 1,000 to 2,000 ppm-an air level that is inadequate, sleepy, and sufficient to cause complaints 
d) 2,000 ~ 5,000ppm-stagnant, old, sultry air level. It is headache and drowsiness, accompanied by
inattention, decreased concentration, rapid heartbeat and slight nausea. 
e)> 5,000 ppm-Exposure to it may cause severe hypoxia, resulting in permanent brain damage, coma and even death.
