Different sensors are used to react with different gases, allowing gas detectors to detect different gases. So, what gases can gas detectors detect;

The types of gases that often require gas detectors to detect in daily work are mainly divided into three categories: combustible gases, toxic gases, and volatile organic compounds (VOCs).

Combustible gas is the most commonly encountered gas in the use of gas detectors. The concept of combustible gas refers to a gas that can be uniformly mixed with air (or oxygen) within a certain concentration range to form a premixed gas. When encountering a fire source, it will explode and release a large amount of energy during the combustion process.

Such gases are commonly present in the working environment of industries such as petrochemicals and chemical manufacturing. Common combustible gases include hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), acetylene (C3H4), acetylene (C4H6), and so on.

Our gas detectors can detect all the combustible gases mentioned above. Some gas detectors only detect one type of gas, while others can detect multiple types of gases.

Toxic gases refer to gases that are harmful to the human body and can cause poisoning. They are mainly divided into irritating gases (referring to gases that have a stimulating effect on the eyes and respiratory mucosa) and suffocating gases (referring to toxic gases that can cause hypoxia in the body. Asphyxiating gases can be divided into pure suffocating gases, blood suffocating gases, and cell suffocating gases);

These gases can directly cause harm to the human body and are also very dangerous. Common toxic gases include carbon monoxide (CO), hydrogen sulfide (H2S), ammonia (NH3), chlorine (CL2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitric oxide (NO), carbon dioxide (CO2), and so on.

The concept of VOC is any organic liquid or solid that can spontaneously evaporate at room temperature and pressure;

Commonly referred to as organic solvents, common gas detectors can detect gasoline, diesel, benzene, crude oil, paint, etc.
