Description of gas detectable by gas detector
Gas detectors are used more and more widely. It is mainly used in petrochemical industry, water treatment industry, military industry, pharmaceutical industry and food industry.
In many pharmaceutical industries, since many raw materials and intermediates are flammable, explosive or toxic chemicals, toxic and harmful or flammable and explosive gases are leaked in the process of chemical production and pharmaceuticals. Choose a suitable flammable gas alarm or gas detector for detection, so that some toxic gases can be effectively checked to ensure effective inspection and safety.
Gas detector is an instrument tool for gas leakage concentration detection or alarm, mainly divided into handheld/fixed gas detectors. It uses gas sensors to detect the types of gases that exist in the environment, and is generally used to detect toxic gases, flammable gases, or oxygen content in gases.
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.
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.
