GS300/GS600 gas leak detector is an optical gas imaging (0Gl:Optical Gas Imaging) equipment. It adopts long-wave infrared refrigeration detector and uses precision narrow-band filter technology. It has extremely high detection sensitivity and can be used for about 20 kinds of gas leakage detection such as sulfur hexafluoride, ethylene, ammonia, etc. Statistics show that gas leakage accidents also conform to the 28th principle, and the 80% leakage is caused by 20% leakage points. GS300 and GS600 series gas leak detectors of Zhengzhou haiwei photoelectric technology co., ltd. adopt the leak detection mode of video images. users can intuitively observe the gas leak through the display screen, can accurately locate the leak location, and the detection process will not affect the normal operation of the tested equipment. Its long-distance, non-contact detection method greatly improves the efficiency of leak detection, thereby significantly reducing the probability of major accidents. It is an essential tool for detecting the operating status of equipment, ensuring safe production, and preventing air pollution.
