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.

Intelligent energy saving, the tester will automatically turn off 5 seconds after completing the test to save power6. The size is 84.5 x 40 x 18.5 mmPrecautions1. Test at least 20 minutes after drinking, because it takes about 20 minutes for alcohol to be absorbed from the digestive system into the blood. If tested immediately after drinking, the result can only reflect the alcohol concentration in the mouth at that time, not the alcohol concentration contained in the blood2. For accurate test results, please wait 20 minutes after drinking before testing, and the test time should be more than 3 minutes from the last test3. Do not wipe the product directly with chemicals or corrosive solvents to prevent liquid from flowing into the air blow pipe4. The machine will not work properly when there is a high concentration of interfering gas5. If the test is performed at low voltage, there will be a certain deviation between the test value and the actual value6. It is strictly forbidden to place and use it in a closed environment with corrosive gases such as pigments, pesticides, alcohol, or polluted air7.
