Description
Overview
GAOTek tunable methane gas leak detector uses tunable laser spectroscopy (TDLAS) technology to quickly and accurately detect gas leaks within a distance of 30 meters. Workers can effectively detect hard-to-reach or even unreachable areas in safe areas, such as busy roads, suspended pipelines, high-rise risers, long-distance transmission pipes, and unmanned rooms. The use not only effectively improves the efficiency and quality of walking inspections, but also enables inspections that were previously inaccessible or difficult to reach.
This product is suitable for overhead pipelines, risers or pipelines distributed in narrow spaces are difficult to reach, and become potential safety hazards; it is difficult to quickly sell leaks during emergency repairs, increasing on-site crisis, and daily pipeline inspections consume a lot of time And manpower, inefficiency, conventional detectors need to be recurring or periodic, and the process is cumbersome and unsuitable.
