As we all know, the density of carbon dioxide is higher than that of the air. When the carbon dioxide is less, it is not harmful to the human body, but when it exceeds a certain amount, it will affect the breathing of people (other organisms as well). The reason is that the concentration of carbonic acid in the blood increases, the acidity increases, and acidosis occurs. The carbon dioxide detector is the 1 instrument specially used to detect the change of carbon dioxide concentration. When its concentration exceeds the alarm value range, it can directly give an on-site sound and light alarm, so as to ensure the safety of on-site personnel. Therefore, before using the carbon dioxide detector, it is necessary to set the alarm value range. What is the general setting of the CO2 detector alarm value range? The following is a brief introduction by yi yun Tian:

the concentration of carbon dioxide gas is harmful to human body:

1, 350 ~ 450ppm: Same as normal outdoor environment.

2, 350 ~ 1000ppm: Fresh air and smooth breathing.

3, 1000 ~ 2000ppm: The air feels cloudy and begins to feel drowsy.

4, 2000 ~ 5000ppm: headache, drowsiness, sluggishness, inability to concentrate, rapid heartbeat, mild nausea.

5, more than 5000ppm: may lead to severe hypoxia, resulting in permanent brain damage, coma and even death.

Therefore, in order to ensure safety, the alarm value range of the carbon dioxide gas detector is generally set within 1000ppm.

of course, due to different application places, the measuring range of carbon dioxide gas detectors from general conventional gas detector manufacturers is 0 ~ 100ppm, 500ppm, 2000ppm, 5000ppm, 10000ppm, 20000ppm, 50000ppm, 20%, 100 Vol. if other measuring ranges are required, yiyuntian can also provide customization. When the gas concentration of the carbon dioxide gas detector exceeds the set range, it can provide an early warning function.
