What gases is the gas detector capable of detecting?
A gas detector is a detection tool used to detect the concentration of leaked gas. It belongs to an electronic type of instrumentation, mainly including portable gas detectors and fixed gas detectors, etc., mainly relying on gas sensors to measure the concentration of various gases. It is widely used in various industries for testing. So what gases can the gas detector detect?
1. Combustible gas
Combustible gas is what we most often encounter in the use of gas detectors. The concept of combustible gas refers to the gas that can be uniformly mixed with air (or oxygen) within a certain concentration range to form a premixed gas that will explode when encountering a fire source. , a gas that releases a large amount of energy during combustion.
Such gases are ubiquitous in the working environment of petrochemical and chemical manufacturing industries. Our common combustible gases are hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane ( C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propyne (C3H4), butyne (C4H6), etc.
All of the above combustible gases can be detected by our gas detectors. Some gas detectors only detect one kind of gas, while others can detect multiple gases.
2. Toxic gas
Toxic gas is a gas that is harmful to the human body and can cause poisoning. It is mainly divided into irritating gas (gas that irritates the eyes and respiratory tract mucous membrane) and suffocating gas (gas that can cause hypoxia in the body). Toxic gas asphyxiating gas can be divided into simple asphyxiating gas, blood asphyxiating gas and cell asphyxiating gas), these gases can directly cause harm to the human body, and are also very dangerous, common toxic gases carbon monoxide (CO), hydrogen sulfide (H2S), ammonia (NH3), chlorine (CL2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitric oxide (NO), carbon dioxide (CO2), etc.
3. VOC (Volatile Organic Compounds)
The concept of VOC is any organic liquid or solid that can spontaneously volatilize under normal temperature and pressure, usually called an organic solvent. Common gas detectors can detect gasoline, diesel, benzene, crude oil, paint, etc.
