Carbon monoxide detectors and combustible gas detectors are very different, many dealers and users often confuse the two. In fact, two very different, believe, will need to use the occasion of carbon monoxide detector installed incorrectly combustible gas detector, combustible gas to the installation of the detector where the carbon monoxide detector installed, it will give people the life bring great loss of property. Carbon monoxide detector is used to detect carbon monoxide (CO) of the. Can not be used to detect methane (CH4) gases such as methane. Combustible gas detector market is usually used to detect natural gas, liquefied petroleum gas or coal gas, etc., the city piped gas is usually in one of these three gases. The main components of these gases is methane (C4H4) gases such as methane, its main feature is has a pungent odor. When the air in the combustible gas concentration exceeds a certain level will cause an explosion. Combustible gas detector is that explosive methane gases, and can not be used to detect carbon monoxide gas. Urban coal gas pipeline is a special gas, which contains both the CO component, but also contains methane gases. So if there is leaking gas pipeline inspection, you can either use the carbon monoxide detector can also be used combustible gas detector. But if you want to test pipeline natural gas, liquefied petroleum gas or coal gas is produced in the combustion of excess carbon monoxide gas, carbon monoxide detector is needed. In addition, the use of coal stoves for heating, is produced by burning coal and other carbon monoxide gas (CO), not methane (CH4) gases such as methane. Therefore, carbon monoxide detector should be used rather than the combustible gas detector. If the use of coal stoves for heating, coal burning combustible gas detector installed where is no use, people were poisoned, the combustible gas detector will not ring. This is very dangerous. In short, if you want to test the toxic gas, is not concerned about the poisoning, be sure to use hand-held or Hunan Guorui fixed carbon monoxide detector. If you want to test the explosive gas, is not concerned about a leaking pipe, commonly used hand-held or Hunan Guorui combustible gas detector fixed on it. Hunan Guorui used detection principle is based on catalytic combustion, testing a variety of combustible gas concentration, with infrared remote control, as well as sound and light alarm, which is widely used in petrochemical, metallurgy, mining, fire, gas, electric power communications, urban water supply, sewage treatment, research, education, and defense.
