The laser methane leak detector utilizes advanced laser spectroscopy technology to accurately detect methane gas leaks. Its working principle is based on the interaction between laser light of a specific wavelength and methane molecules, and it determines the methane concentration by analyzing the reflected or scattered light signals. The outer shell is made of high - strength, impact - resistant materials to adapt to complex and harsh detection environments such as outdoors and in mines. The internal optical system is precisely calibrated to ensure high - precision laser emission and reception. Its advantage lies in its extremely high detection sensitivity, capable of detecting even trace amounts of methane leaks; long detection distance, enabling the discovery of leak points from a relatively long distance; and fast response speed, providing detection results quickly. It is widely used in fields such as natural gas pipeline inspection, coal mine gas monitoring, and urban gas facility detection to effectively prevent safety accidents caused by methane leaks.
