Hydrogen gas detectors are one of the safety measures for the hydrogen energy industry

Hydrogen gas detector

As we all know, hydrogen is a clean energy source, like traditional energy sources such as natural gas, liquefied petroleum gas, and gasoline, it not only has high energy but also has a particular risk of deflagration, which is a flammable gas with fire hazard class A (the explosion limit of hydrogen (LEL%) is 4%VOL-75%VOL). In addition, hydrogen gas also has its own unique characteristics: first, colorless, tasteless, and odorless, the human body can not sense its leakage; second, the existence of "hydrogen corrosion" phenomenon, easy to embrittle the metal and leakage; third, low ignition energy, combustion, and explosion range is wide; fourth, low density, fast diffusion, the diffusion rate is 3.8 times and 12 times that of natural gas and gasoline, respectively The diffusion rate is 3.8 times and 12 times faster than that of natural gas and petrol respectively.

Once hydrogen is ignited, it burns fast, and once it leaks in the process of manufacture, storage, and handling, it can be mixed with air to form an explosive mixture, which will explode when it meets heat or open flame.
