Introduction of alarm value of carbon dioxide gas detector
As one of the most common hydrocarbons, carbon dioxide is a colorless and odorless gas at normal temperature and pressure. It is one of the components of air and a common greenhouse gas. Although carbon dioxide is non-toxic and will not burn, inhaling too much carbon dioxide at one time will lead to suffocation, and accidents caused by carbon dioxide leakage will occur from time to time. Therefore, in places where carbon dioxide may leak, a carbon dioxide gas detector is needed in addition to necessary ventilation, so what is the appropriate alarm value of the carbon dioxide gas detector?
The concentration of carbon dioxide in the air is 0.04%, which is about 400ppm. At this time, carbon dioxide will not do any harm to human body. The human body is very sensitive to the increase of carbon dioxide concentration. When the concentration of carbon dioxide in the environment reaches 1000ppm, chest tightness, shortness of breath, inattention and drowsiness will occur. When it reaches 2000ppm, there will be headaches, lethargy, sluggishness, rapid heartbeat and nausea. When the concentration of carbon dioxide exceeds 5000ppm, severe hypoxia will occur, causing permanent brain damage, coma and even direct death. So in order to ensure safety, the alarm value of carbon dioxide gas detector is generally set within 1000ppm.
Carbon dioxide detector is widely used in the following aspects. Industrial production and processing: underground, coal mine and other limited space operations, metal processing, paper making, solvent extraction and other industries related to carbon dioxide.
Animal husbandry and aquaculture: a lot of carbon dioxide will be released during the growth and development of animals, and it is very easy to cause diseases among animals under unfavorable ventilation, so it is necessary to detect carbon dioxide and ammonia in farms.
Public places: in some crowded public places, such as schools, hospitals, office buildings, shopping malls, parking lots and other environments.
For the detection of carbon dioxide in the environment, ERUN-PG71S6-C2, a hand-held pump-type carbon dioxide detector produced and sold by Winrun Environmental Protection, can be used. This instrument adopts pump-type measurement, and the air inlet can be equipped with a filter to filter the dust and water vapor in the gas to be detected. Imported gas sensor is adopted, which has high precision and fast response. The data storage capacity is large, which can save 100,000 pieces of data and support wireless data transmission. The instrument has excellent performance and is widely used in the detection of carbon dioxide.
