Although natural gas is lighter than air and is easy to diverge, but when natural gas accumulate in the house or other closed environment and reaches a certain proportion, it will trigger a powerful explosion. The explosion may level the entire house, and even bring disaster to the neighboring buildings. By the way, the explosion lower limit of methane in air is 5%, and the upper limit is15%.
In view of the harm of above leakage of natural gas, in order to monitor whether there is a gas leak and to protect our life safety, gas detector has become the necessary safety equipment. Gas detectors can alert people in the initial stage of natural gas leakage, which will be helpful to prevent the happening of accidents.
