Timely measures can avoid the gas explosion.


the explosion limit of combustible gas is generally expressed by volume percentage concentration.The explosion limit is the general term for the lower explosion limit and the upper explosion limit. The concentration of combustible gas in the air will explode only when it reaches the lower explosion limit and the upper explosion limit setting point. For various combustible gases, according to the setting of the combustible gas alarm, the detection range of the combustible gas alarm is usually 0~100 LEL. For combustible gas alarms, generally fixed alarms can be divided into 2 alarm points: low report and high report, low report of 20% LEL is primary alarm, high report of 50% LEL is secondary alarm. Portable combustible gas alarm is usually provided with an alarm point: 25% LEL is the alarm point.
