reflective object (such as the ground, valves, pipes, walls, etc.) and diffusely reflects, and part of the laser returns to the detection unit of the instrument. In the beam path, if there is an air mass formed by the leakage of the measured gas, the air mass will absorb the detection laser. The ratio of the amount of unabsorbed light to the amount of absorbed light is proportional to the concent

This is a device for non-contact measurement of natural gas (CH4) concentration based on laser absorption spectroscopy. When the instrument is working, it emits a specific wavelength range (the center wavelength is not the same for different gases under test)of the detection laser, which is diffusely reflected when it ments reflector (e.g. the ground, valves, pipelines, walls, etc.), and part of
