What gases can be detected by combustible gas detectors?
General combustible gases can be detected by combustible gas detectors, such as 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, cyclohexane, propylene, dimethylamine, acetic acid, formaldehyde, diesel, gasoline, acetic acid, ethanol, solvent oil, epoxyethane, dimethyl sulfate, sulfur hexafluoride, methyl ether, isobutane, dimethyl ether, turpentine, oil and gas, paints, gases, benzyl alcohol, dichlorotoluene, methyl acetate, methyl acetate, etc.
The application fields of combustible gas detectors are very wide, such as petrochemicals, industrial production, smelting and forging, electricity, coal mines, tunnel engineering, environmental monitoring, sewage treatment, biopharmaceuticals, household environmental protection, animal husbandry, greenhouse cultivation, warehousing and logistics, brewing and fermentation, agricultural production and fire protection, gas, construction, municipal enterprises, school laboratories, scientific research centers and other places that require the use of gas detectors.
The detection principle varies depending on the gas being detected
1. Catalytic combustion principle: Combustible gases such as methane, hydrogen, etc;
2. Electrochemical principles: such as oxygen, carbon monoxide, hydrogen, ammonia, sulfur dioxide, hydrogen sulfide, nitrogen oxides, hydrogen fluoride, chlorine gas, etc;
3. Infrared principle: carbon dioxide, methane, bromomethane, oil and gas, etc;
4. PID photoionization principle: VOC, TVOC, benzene, xylene, etc;
5. Thermal conductivity principle: see examples such as fluorine gas, nitrous oxide, sulfur hexafluoride, etc
6. Non dispersive infrared (dual beam) NDIR principle: such as carbon dioxide, carbon monoxide, sulfur dioxide, etc
7. Other gas detection principles on the market include laser detection, ultraviolet principle, VOC detection, and FID detection principle.
