Description

Technical Field

[0001] The utility model relates to the technical field of CO concentration detection, in particular to a portable CO concentration detection device. Background Art

[0002] Pure carbon monoxide is a colorless, odorless, non-irritating gas. It has a very low solubility in water, but is easily soluble in ammonia water. After carbon monoxide enters the human body, it will combine with hemoglobin in the blood, which will prevent hemoglobin from combining with oxygen, causing hypoxia in the body tissues and leading to suffocation and death. Therefore, carbon monoxide is toxic. Carbon monoxide is a colorless, odorless, and tasteless gas, so it is easy to ignore and cause poisoning. In a working environment where carbon monoxide is easily generated, it is not only necessary to set up a fixed carbon monoxide detection device, but also to carry the detection equipment manually for regular patrols. When personnel conduct regular patrols and inspections, the carbon monoxide detection device is not portable. When it is used in some narrow environments that cannot be reached by human hands or some high places, the device cannot reach the detection point for detection, which is extremely inconvenient to use, and it is also easy to cause some detection points to be missed. For this reason, we propose a portable CO concentration detection device. Utility Model Content
