Product Introduction: The SF6 gas quantitative leak detector is a high-precision testing equipment primarily used for detecting SF6 gas leaks in devices such as high-voltage switchgear, transformers, and substations. It combines an optical system with an electronic control system to accurately measure the concentration of SF6 gas. Additionally, it is equipped with various automated control and alarm functions to ensure the safe and stable operation of the equipment. By using this leak detector, users can promptly detect and address SF6 gas leaks, thereby ensuring the normal operation of the power system. The working principle of this leak detector is primarily based on non-dispersive infrared (NDIR) technology and chemical sensitivity sensors. During the detection process, SF6 gas is introduced into the measurement unit inside the instrument through a gas sampling pipeline. The gas then passes through an adjustable optical path and a chemical sensitivity sensor in sequence, ultimately resulting in an accurate concentration value.
