The following common flammable gases can be detected by flammable gas detectors: hydrogen, methane, ethane, propane, butane, nonane, methanol, ethanol, propanol, ethylene, ethyl acetate, toluene, xylene, acetone, Butanone, vinyl chloride, liquefied gas, natural gas, acetylene, acrylonitrile, methane, cycl Methyl ester, sulfur hexafluoride, methyl ether, isobutane, dimethyl ether, turpentine, oil and gas and other flammable gases, paints, gases, benzyl alcohol, dichlorotoluene, methyl acetate, etc. are a few examples of substances that can burn when exposed to heat.
Combustible gas detectors are employed in a variety of industries, including petrochemical production, industrial production, smelting and forging, electric power, coal mines, tunnel engineering, environmental monitoring, sewage treatment, biopharmaceuticals, home environmental protection, animal husbandry, greenhouse cultivation, warehousing and logistics, brewing and fermentation, agricultural production, and fire protection, gas, building construction, municipal enterprises, and school lanes.
Depending on the detected gas, the detection principle is also different:
1. Principle of catalytic combustion: combustible gas, methane, hydrogen and other combustible gases;
2. Electrochemical principle: such as oxygen, carbon monoxide, hydrogen, ammonia, sulfur dioxide, hydrogen sulfide, nitrogen oxides, hydrogen fluoride, chlorine, etc.;
3. Infrared principle: carbon dioxide, methane, methyl bromide, oil and gas, etc.;
4. PID photoion principle: VOC, TVOC, stupid, xylene, etc.;
5. Principle of thermal conductivity: see such as fluorine gas, nitrous oxide, sulfur hexafluoride, etc.
6. Non-dispersive infrared (dual beam) NDIR (Dual Beam) principle: such as carbon dioxide, carbon monoxide, sulfur dioxide, etc.
7. Other gas detection principles on the market include laser detection, UV principle, VOC and FID detection principle.
