Carbon dioxide gas detector alarm value
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, there is a risk of suffocation if inhaled too much carbon dioxide at one time, and accidents caused by carbon dioxide leakage occur from time to time. Therefore, in places where carbon dioxide may leak, it is necessary to use carbon dioxide in addition to necessary ventilation. Gas detector, so how much should the alarm value of the carbon dioxide gas detector be set to?
The concentration of carbon dioxide in the air is 0.04%, which is about 400ppm. At this time, carbon dioxide will not cause any damage to the human body. The human body is very sensitive to the increase in the concentration of carbon dioxide. 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, headaches, lethargy, sluggishness, rapid heartbeat, and nausea will occur. When the carbon dioxide concentration exceeds 5000ppm, severe hypoxia will occur, causing permanent brain damage, coma or even direct death. Therefore, in order to ensure safety, the alarm value of carbon dioxide gas detector is generally set within 1000ppm.
Carbon dioxide detectors are widely used and are mainly 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: During the growth and development of animals, a lot of carbon dioxide will be released. In the case of unfavorable ventilation, it is very easy to cause disease outbreaks among animals. Therefore, carbon dioxide and ammonia gas need to be detected in the farm.
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, you can use the hand-held pump-suction carbon dioxide detector ERUN-PG71S6-C2 produced and sold by Yingrun Environmental Protection. This instrument uses pump-suction measurement, and the air inlet can be equipped with a filter. dust and water vapor filtration. Imported gas sensor with high precision and fast response. The data storage capacity is large, can save 100,000 pieces of data, and supports wireless data transmission. The performance of the instrument is excellent, and it is widely used in the detection of carbon dioxide.
