Mainly used for:
Medical and disease control public places, occupational health testing. In densely populated places such as conference rooms, classrooms, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, train stations, entertainment halls, etc., carbon dioxide detectors can be used for environmental quality monitoring. To ensure people's physical health.
Agricultural carbon dioxide is related to plant photosynthesis. Appropriate concentration of gas fertilizer can increase the yield of agricultural crops.
Livestock breeding industry. The quality of air is related to the healthy growth of animals. If the air remains turbid for a long time, with high carbon dioxide concentration and no ventilation, it can lead to animal diseases or outbreaks of diseases. Therefore, using carbon dioxide detectors in breeding farms can prevent the occurrence of animal epidemics.

Industry. Carbon dioxide detectors are widely used in industry, such as wastewater treatment, safety production, and especially underground operations, which require monitoring of carbon dioxide concentration. Carbon dioxide detectors are commonly used in industries related to carbon dioxide, such as metal processing, pulp and paper, cleaning and solvent extraction, and low-temperature cleaning.
