【Prevent gas explosion】Our gas detector can monitor the concentration of gas in the air in real time. When a gas leak exceeds the standard, the detector issues awarning until the ambient gas volume falls below the alarm point.【Combustible gas detection】The gas detector is mainly used to detect natural gas (main components: methane), liquefied gas (main components: butane, propane) andmunicipal coal gas (alkane, olefin, arene).【Gas concentration display】The screen will show the real-time gas concentration in the air. When it exceeds 8% LEL, the detector will alarm.【Voice alarm and strobe light warning】Loud sound and strobe light can effectively remind users, especially for the elderly.
