Toxicity of Carbon Monoxide
Carbon monoxide is the toxic gas which has no color, no odor, no irritation, and cannot be perceived by human sense organs. It can inhibit the oxygen carrying ability of blood. The carbon monoxide mainly affects the supply and utilization of oxygen. Its affinity with red blood cell is much higher than that of oxygen with red blood cell by over 300 times. The inhalation of carbon monoxide would cause body hypoxia.

When the carbon monoxide is inhaled into the human body, it gets into the lung, and combines with the red blood cells first to let the red blood cell lose the ability of delivering the oxygen, resulting in hypoxia of multiple human organs, and then leading to tissue damage and even death. Generally, people cannot be aware of that when encountering accidental poisoning, and often are found in the coma state. That would lead to serious injury and even death. So, the carbon monoxide is often called the invisible killer in household.

Generally, the carbon monoxide in the family comes from the faulty water heater, gas cooker, gasoline engine or other carbon monoxide source. People getting poisoned mainly happens for the reasons like improper use of gas, improper operation for using furnace indoors, enjoying the chafing dish of the type using charcoal, sleeping in the vehicle with the air conditioner open, and large quantity of carbon monoxide gas generated by the vehicle exhaust in the basement.

Product Introduction
The carbon monoxide detector detects the carbon monoxide concentration in the air via the carbon monoxide sensor, and generates the electric signal whose intensity degree is associated with the concentration of carbon monoxide. It mainly works for detecting the carbon monoxide leakage. Our product utilizes the carbon monoxide for calibration with the calibration concentration of 100ppm. Before leaving the factory, it needs to be processed with the ageing for 24 hours. The ex-factory pass rate is 99%.

With the function of software controlled calibration available, the carbon monoxide detector would carry out the self checking to sensor and the function of sound and flash alarm after being connected to the power source. It has the automatic protection function of prevention from the impact of high concentration gas. The product has high precision and high sensitivity. It is very important for guarding the security of the family. We suggest each family should have at least one such carbon monoxide detector. In addition, the carbon monoxide may appear at any layer of the household. It may not reach the layer that is already mounted with the device. So, for the sake of the safety of whole family, we suggest to mount such a product on each layer.
