Fire Alarm
Traditional fire detectors are mostly based on changes in physical characteristics such as temperature, smoke and flame. This detection method is difficult to reliably detect early fire hazards.
Underground Pipe Network
Compared with other transportation methods, underground natural gas pipeline transportation has the characteristics of low maintenance cost and high safety.
Mine Alarm
Marsh gas is an unconventional natural gas produced naturally in coal seams, also known as coal-bed methane. It will be released as the coal is mined.
Oil And Gas Recovery
Oil and gas are organic compounds that will volatilize into the air during refueling, unloading and storage at gas stations. The main components are methane (CH4) and propane (C3H8) gas.
NDIR Technology
The infrared light is directed by the infrared source passing through the gas chamber towards the detector.CO2 molecules inside the gas chamber will only absorb a specific wavelength of the light.
