Hand-held laser remote methane gas leak detector (JJB30)
1. Overview
The Hand-held laser remote 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.
2. Features
◆ Safety level: intrinsically safe explosion-proof design;
◆ Detection distance: detection of methane and methane-containing gas leakage at a distance of 30 meters;
◆ Fast detection: the detection time is only 0.1 seconds;
◆ High accuracy: specific laser detection, only reacting to methane gas, not affected by environmental conditions
◆ Easy to use: automatic detection at startup, no need for periodic calibration, basic maintenance free
◆ Easy to carry: the design is in line with human-computer function, small size and easy to carry
◆ Friendly interface: system-based operation interface, closer to users;
◆ Ranging function: integrated distance measurement function;
◆ Excessive work: more than 10 hours of testing can be achieved in standard mode;
◆ Removable battery for easy replacement and extended working hours;
◆ 3.2 inch screen/Touch screen mode
