Which gases can be detected by combustible gas detectors?
Generally, combustible gas detectors can detect combustible gases, 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 other combustible gases, paints, gases, benzyl alcohol, dichlorotoluene, methyl acetate, methyl acetate, and so on.
Combustible gas detectors are widely used in various fields, 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, research centers, and so on.
The detection principle varies depending on the type of 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. Principle of Non Dispersed Infrared (Dual Beam) NDIR (Dual Beam): such as carbon dioxide, carbon monoxide, sulfur dioxide, etc
7. Other gas detection principles on the market include laser detection, ultraviolet principle, VOC, and FID detection principle.
