Alarm value of carbon dioxide gas detector
Carbon dioxide, as one of the most common hydrocarbons, is a colorless and odorless gas at room temperature and pressure. It is a component of air and a common greenhouse gas. Although carbon dioxide is non-toxic and does not burn, inhaling excessive amounts of carbon dioxide can pose a risk of suffocation. Accidents caused by carbon dioxide leakage often occur. Therefore, in places where carbon dioxide may leak, in addition to necessary ventilation treatment, a carbon dioxide gas detector is also required. What is the appropriate alarm value for the carbon dioxide gas detector?
The concentration of carbon dioxide in the air is 0.04%, about 400ppm, at which point carbon dioxide will not cause any harm to the human body. The human body is very sensitive to the increase in carbon dioxide concentration. When the concentration of carbon dioxide in the environment reaches 1000ppm, chest tightness, shortness of breath, lack of concentration, and drowsiness can occur. When reaching 2000ppm, symptoms such as headache, drowsiness, dullness, accelerated heartbeat, and nausea will occur. When the concentration of carbon dioxide exceeds 5000ppm, severe hypoxia can occur, causing permanent brain damage, coma, and even direct death. So to ensure safety, the alarm value of the carbon dioxide gas detector is generally set within 1000ppm.
Carbon dioxide detectors have a wide range of applications, mainly used in the following areas. Industrial production and processing: limited space operations such as underground and coal mines, metal processing, papermaking, solvent extraction, and other industries related to carbon dioxide.
Animal husbandry: During the growth and development of animals, a lot of carbon dioxide is released, which can easily lead to outbreaks of diseases between animals under poor ventilation. Therefore, carbon dioxide and ammonia gas need to be tested in breeding farms.
Public places: In densely populated public places such as schools, hospitals, office buildings, shopping malls, parking lots, etc.
For the detection of carbon dioxide in the environment, the handheld pump suction type carbon dioxide detector ERUN-PG71S6-C2 produced and sold by Yingrun Environmental Protection can be used. This instrument adopts a pump suction measurement method, and the air inlet can be equipped with a filter to filter the dust and water vapor in the measured gas. Adopting imported gas sensors, with high accuracy and fast response. Large data storage capacity, capable of storing 100000 pieces of data, supporting wireless data transmission. The instrument has excellent performance and is widely used in detecting carbon dioxide.
