Gas detectors are very important safety devices that can help us promptly detect excessive concentrations of harmful gases in the air, thus preventing accidents such as poisoning or suffocation. Its wide application is not limited to industrial production sites and chemical laboratories, but also extends to many fields such as coal mining and environmental monitoring.
The gas alarm can detect the following harmful gases:
1、 Toxic Gases:
（1）Carbon monoxide (CO)
（2） Sulfur dioxide （SO2）
（3） Ammonia （NH ₃）
（4）Hydrogen sulfide (H2S)
（5）Chlorine （Cl2）
（6） Cyanide (HCN)
（7） Ozone (O3)
（8）Nitrogen dioxide (NO2)
（9） Hydrogen fluoride（HF）
These gases pose a great threat to human health. Once inhaled in excessive amounts, they may lead to poisoning and even endanger life. Therefore, by using gas detectors to monitor and alarm these toxic gases in real time, measures can be taken promptly to protect people’s lives and safety.
2、 Flammable Gases:
（1）Methane (CH4)
（2） Propane (C3H8)
（3） Ethylene (C2H4)
（4） Butane (C4H10)
（5） Hydrogen（H2）
（6） Natural Gas（Natural Gas）
（7） Liquefied Petroleum Gas (LPG)
These gases are widely present in industrial production, energy supply and daily life. Once they leak or accumulate to a certain concentration, they may cause serious accidents such as fires or explosions. Therefore, real-time monitoring and alarm of these gases through gas detectors can effectively prevent and control safety risks.
3、 Specific Ambient Gases:
（1）Oxygen (O2)
（2） Carbon dioxide(CO2)
（3） Helium（He）
（4） Argon （Ar）
Although these gases may not necessarily be flammable or toxic, changes in their concentrations may also affect personnel safety and the normal operation of equipment. For instance, too low an oxygen concentration may cause suffocation in people, while too high a carbon dioxide concentration may accelerate the corrosion and aging of equipment. Therefore, the monitoring of these gases through gas alarms is equally important.
It should be noted that the above are just some common types of gases. In fact, gas detectors can be customized for specific industries or application scenarios to detect more different types of gases.
Gas detectors can detect a wide variety of flammable gases, toxic gases and specific harmful gases. By making reasonable choices and using gas detectors, we can achieve real-time monitoring and alarm of various harmful gases in the air, thereby effectively preventing and controlling safety risks.
