KN801 Portable Carbon Monoxide Detector Voice Type For Petroleum Industries
Carbon monoxide (CO) is a colorless, odorless.and non-irritating gas. The molecular weight is 28.01, the density is 1.250g/l, the freezing point is -207'C , and the boiling point is -190°C. It has a low solubility in water, but is easily soluble in ammonia water. Explosion limit in air12.5%~74%.After carbon monoxide enters the human body, it binds to hemoglobin in the blood oxygen, which will prevents hemoglobin from binding to oxygen.causing hypoxia in the body tissues and leading to suffocation and death.
Therefore, carbon monoxide has toxicity. Carbon monoxide is a colorless and odorless gas.which is easy to ignore and lead to poisoning. The detector can detect gas leakage sources in limited space and has functions such as alarm, one hand operation, and other convenient functions.
♦ High sensitivity; Quick response
KN801 is widely used in gas detection fields in industries such as petroleum, chemical, coal mining, metallurgy paper making, fire protection, municipal telecommunications, food, textile, etc
