Pure carbon monoxide (CO) is colorless, odorless, and non-irritant gas: molecular weight: 28. 01; Density: 1. 250g/ l; freezing point: - 207C; boiling point: - 190C. Its solubility in water is quite low, but it dissolves instantly in ammonia water. Air mixed explosion limit is between 12. 5% and 74%. After entering human body, carbon monoxide will combine with hemoglobin in blood, making the hemoglobin not able to combine with oxygen, which causes oxygen deficit to organism organization, leading to death from suffocation. Therefore, carbon monoxide is toxic, and is colorless, odorless, and tasteless, which is easy to be ignored and thus causing poisoning. The carbon monoxide detector can detect the concentration of carbon monoxide gas, and observe the value of carbon monoxide gas concentration at any time. It has a very clear large LCD screen, sound and light alarm prompts, to ensure that dangerous gases can be detected under very unfavorable working environments and prompt operators to prevent them in time. It is widely used in petroleum, chemical, coal, metallurgy, papermaking, fire fighting, municipal administration, telecommunications, food, textile and other industries. 1.
