The methane gas sensor is designed specifically for vehicle use. Methane (CH4) is the primary component in CNG and LNG fuels. Methane gas is lighter than air and can be flammable in concentrations ranging from 5% to 15% volume in atmosphere. The methane gas sensor is
designed to provide detection of methane gas in concentrations below the Lower
Flammability Limit (LFL) of methane, more specifically 20% of the LFL for trace alarm and
50% of the LFL for significant alarm. Methane gas sensors are anodized silver.
Sensor has a five (5) year shelf life while sealed in shipping bag and a maximum four (4) year
service life.
