What is the normal range of carbon monoxide ?

The concentration of carbon monoxide in the air will cause harm to human body:

1. The content of carbon monoxide in the air reaches 50ppm, and adults are allowed to be exposed to the large content of carbon monoxide. If the content exceeds this level, it will cause harm to the human body;

2. The content of carbon monoxide in the air reaches 200ppm. Adults will have mild headache, dizziness, nausea and other adverse symptoms after being exposed to it for 2-3 hours;

3. The content of carbon monoxide in the air reaches 400 ppm. Adults will suffer from forehead pain within 2 hours after exposure, and will be in danger of life after 3 hours;

4. The content of carbon monoxide in the air reaches 800 ppm. Adults have headache and nausea within 45 minutes and die within 2-3 hours;

5. The content of carbon monoxide in the air reaches 1600 ppm, causing headache and nausea within 20 minutes and death within 1 hour;

It can be seen from the above data that as long as the content of CO in the air exceeds 50ppm, it will cause harm to human body. Once this range is exceeded, we need to use gas leak and carbon monoxide detectors. The detection range of the gas leak and carbon monoxide detectors like Sumring is 0~50, 100, 500, 1000, 2000, 5000, 10000, 100000ppm, 100% LEL and 100% Vol. You can select the appropriate gas leak and carbon monoxide detectors according to the specific conditions to better ensure your personal safety.
