Carbon Monoxide Levels Chart -

Carbon monoxide exposure is the most common method of death by poisoning in the world. The effects of carbon monoxide poisoning are well understood. CO gas competes with oxygen to bind with hemoglobin in the blood leading to a reduction of oxygen in the brain. Even low carbon monoxide levels over long periods can have an impact on brain chemistry.

Gas Sensors Carbon Monoxide (CO) -

Carbon monoxide is a colorless, odorless, toxic gas. It is predominately produced by incomplete combustion of carbon-containing materials. Incomplete combustion occurs when insufficient oxygen is used in the fuel (hydrocarbon) burning process. Consequently, more carbon monoxide than carbon dioxide is emitted.
