Description

Technical Field

[0001] The utility model relates to the technical field of methane detection, in particular to a non-contact laser methane detector. Background Art

[0002] The non-contact laser methane detector is a device that uses laser technology to detect the methane concentration in the environment. It uses a laser beam to irradiate the surface of the object being tested and determines the methane concentration in the target object by measuring the reflected or absorbed laser signal. This detection instrument has the characteristics of fast, accurate, and pollution-free, and is suitable for industrial production, environmental monitoring, safety protection and other fields;

[0003] Since the laser methane detector produces detection results through the interaction between the laser beam and methane gas during use, as the device is used for a longer time, impurities are easily accumulated on the outer wall of the protective glass. Once too many impurities block the outer wall of the glass, it will directly affect the emission of the laser beam and thus directly affect the subsequent detection results. However, the existing devices have not made improvements to this problem, and the overall practical effect is poor. Utility Model Content
