Description
Smart Linkage
When natural gas detected, the device will automatically shut off the valve and turn on the exhausting fan


Natural Gas Detection
A gas alarm is designed to detect combustible gases like methane (CH4). It uses sensors to measure the concentration of methane in the air, which helps in early detection of gas leaks
Installation Position
Install the methane detector at a height of 30 cm from the ceiling, because methane is lighter than air and will rise.
Install the LPG detector at a height of about 15 cm to 30 cm from the ground, because LPG is heavier than air.


Recommended Application Scenarios
Gas detectors should be installed in kitchens and near other appliances that use gas, such as stoves and kitchen of the B&B, to quickly detect gas leaks.
