Wide range of applications for gas detectors
The application of gas detector is getting wider and wider. Mainly used in the petrochemical industry, water treatment industry, ** industry, pharmaceutical industry, as well as the food industry have a wide range of applications.
In many of the pharmaceutical industry, due to many raw materials and intermediates for the flammable and explosive or toxic chemicals, in the chemical production of pharmaceuticals in the process of toxic and harmful or flammable and explosive gas leakage. Choose the right combustible gas alarm or gas detector to detect, so that you can effectively check for some toxic gases, to ensure that you can effectively check to ensure safety.
Gas detector, is a gas leakage concentration detection or alarm instrumentation tools, mainly divided into handheld / fixed gas detector. It is the use of gas sensors to detect the presence of gas species in the environment, generally used to detect toxic gases, combustible gases or gas oxygen content.
Combustible gas is our gas detector in the use of * often encountered, the concept of combustible gases refers to the ability to mix uniformly with air (or oxygen) in a certain concentration range to form a premixed gas, will explode when encountered with an ignition source, the combustion process releases a large amount of energy in the gas.
Such gases in the petrochemical and chemical manufacturing industries are widespread in the working environment, we commonly combustible gases are hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propene (C3H6), butene (C4H8), acetylene (C2H2), acetylene (C3H4), Butyne (C4H6), and so on.
Toxic gases, is harmful to the human body, can cause poisoning of the gas, it is mainly divided into irritant gases (refers to the eye and respiratory mucous membranes have irritating effect of the gas) and asphyxiating gases (refers to the body can be caused by the lack of oxygen of the toxic gases asphyxiating gases can be divided into simple asphyxiating gases, blood asphyxiating gases and cellular asphyxiating gases), these gases can be directly on the human body to cause harm, but also very dangerous. Dangerous, common toxic gases are 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.
