What is a CO carbon monoxide alarm ?
Nowadays, people’s safety awareness has increased and they will install carbon monoxide alarms at home. What is a co carbon monoxide alarm?
Carbon monoxide (CO) gas is a colorless, odorless, non-irritating, toxic gas that cannot be sensed by the five senses, and can inhibit the blood’s ability to carry oxygen. The toxicity of carbon monoxide mainly affects the supply and utilization of oxygen. The affinity of carbon monoxide with red blood cells is more than 300 times greater than the affinity of oxygen with red blood cells, causing hypoxia in human tissues. When carbon monoxide gas is inhaled, carbon monoxide enters the lungs and preemptively combines with red blood cells, making the red blood cells lose the ability to transport oxygen, resulting in the lack of oxygen in multiple organs of the human body, resulting in tissue damage and even death. Ordinary people cannot be aware of themselves when they are accidentally poisoned. They are often found in a coma when they are found, causing serious injury or even death. Therefore, it is not excessive to call it the “invisible killer” in the family. In order to eliminate this invisible killer, we need to install a co carbon monoxide alarm.
The co carbon monoxide alarm uses a carbon monoxide sensor to sense the concentration of carbon monoxide gas in the air and converts it into an electrical signal. The magnitude of the electrical signal is related to the concentration of carbon monoxide. CO carbon monoxide alarms are classified according to the sensors used, generally divided into semiconductor CO carbon monoxide alarms, electrochemical co carbon monoxide alarms, infrared co carbon monoxide alarms, etc. From the perspective of measurement sensitivity, accuracy, stability, and resistance to cross-gas interference, the performance is the best It is infrared co carbon monoxide alarm, but it is more expensive and suitable for laboratory use. The civilian ones are generally semiconductor and electrochemical co carbon monoxide alarms. Such as the below co carbon monoxide alarm：
