The common toxic gases are oxygen, carbon dioxide, carbon monoxide, sulfur dioxide, chlorine, hydrogen sulfide, ammonia, hydrogen cyanide, formaldehyde, ozone, nitric oxide, nitrogen dioxide, Tetrahydrothiophene and so on. According to the harm to the human body, toxic gases can be divided into nerve paralysis gas, respiratory system paralysis gas and muscle paralysis gas; According to the principle of injury to the human body, irritant gas and asphyxiating gas can be considered.

Irritant gas: it refers to the gas that has an irritant effect on eyes and respiratory tract mucosa. It is a toxic gas often encountered in the chemical industry. There are many kinds of irritant gases, the most common are chlorine, ammonia, nitrogen oxides, phosgene (commonly used with insecticides), hydrogen fluoride (mainly used as the raw material of fluorine-containing compounds), sulfur dioxide (used as organic solvents and refrigerants, and used to refine various lubricating oils), sulfur trioxide and dimethyl sulfate, etc.

Asphyxiating gas: refers to the toxic gas that can cause hypoxia. Asphyxiating gas can be divided into simple asphyxiating gas, blood asphyxiating gas and cell asphyxiating gas. Such as nitrogen, methane, ethane, ethylene, carbon monoxide, nitro.

The toxic reactions were dizziness, nausea, vomiting, coma, and some poisonous gases caused skin ulceration and tracheal mucosa ulceration. The state of deep poisoning is shocking, even death. At the same time, it is also used in the fields of insecticides, various chemicals, and so on.

OC-F08 gas detector: it is used to detect poisonous gas in the surrounding atmosphere and play the role of safety warning. The toxic gas detector samples the electrical signal on the sensor, and after internal data processing, outputs 4 ~ 20mA signal output or RS485 signal output corresponding to the ambient gas concentration, using industrial-grade imported sensors, so as to meet the application and installation needs of users on site.
