How to use carbon dioxide analyzer safely and reasonably

The evolution of different environments for industrial progress has also been restricted. Economy and health should be grasped at the same time, so that our life can be better. Therefore, the reasonable use of various instruments and meters can reasonably adjust the harm of this pollution to us.
1. Properties of carbon dioxide
Relative molecular mass Melting point (degrees Celsius) Boiling point (degrees Celsius)
44.01 -78.48 (sublimation) -56.6 (5270 Pa)
Properties Solubility
Colorless, odorless gas. It can be dissolved in water at room temperature and partially generate carbonic acid. It can be dissolved in water (volume ratio 1:1) to generate carbonic acid.
Structural formula Molecular formula Relative density
O=C=O CO2 Relative density 1.101 (-37℃)
2. The harm of carbon dioxide
 The temperature on the earth is getting higher and higher now, which is caused by the increase of carbon dioxide. Because carbon dioxide has the function of heat preservation, now there are more and more members of this group, which makes the temperature rise, and it becomes more and more important. In the past 100 years, the global temperature has risen by 0.6℃. If this continues, it is expected that by the middle of the 21st century, the global temperature will rise by 1.5-4.5℃.
Sea level rise is also caused by the increase of carbon dioxide. In the past 100 years, the sea level has risen by 14 cm. By the middle of the 21st century, the sea level will rise by 25-140 cm. The rise in sea level will cause the Amazon rainforest to disappear and all the ice in the polar oceans to melt. All these changes are tantamount to a catastrophe for wild animals.
The air contains about 0.03% carbon dioxide, but due to human activities (such as the burning of fossil fuels), the carbon dioxide content has soared in recent years, leading to the greenhouse effect, global warming, melting glaciers, and rising sea levels... The Kyoto Protocol, which aims to curb excessive carbon dioxide emissions, has come into effect, and it is expected to curb the greenhouse effect through international cooperation.
3. Effects of different concentrations of carbon dioxide on the human body (carbon dioxide detector)
350-450ppm Same as general outdoor environment 
350-1000ppm Fresh air, smooth breathing
1000-2000ppm Feeling turbid air and start to feel drowsy
2000-5000ppm Feeling headache, drowsiness, dullness, inability to concentrate, rapid heartbeat, mild nausea
More than 5000ppm may cause severe hypoxia, permanent brain damage, coma, or even death
4. Production of carbon dioxide (carbon dioxide detector)
 (1) All organic matter (including animals and plants) can release CO2 during decomposition, fermentation, decay, and deterioration.   
 (2) CO2 is also released during the combustion of petroleum, paraffin, coal, and natural gas.   
 (3) Petroleum and coal also release CO2 during the production of chemical products.   
 (4) All feces and humic acid can also release CO2 during fermentation and maturation.   
 (5) All animals breathe in oxygen and exhale CO2 during breathing.   
(6) All green plants absorb CO22 and release oxygen to carry out photosynthesis. (Carbon dioxide detector)
Carbon dioxide is widely used in industry. For the sake of social and personal safety, industrial enterprises are reminded that it is best to purchase combustible gas detectors to conduct scientific testing and inspections, so as to contribute to creating a clear blue sky.
