In the field of high voltage, ultra-high voltage, and ultra-high voltage switches, SF6 gas is used as an insulation and arc extinguishing medium. However, SF6 high voltage switches are mostly installed indoors, and the air flow is relatively slow. Once SF6 gas leaks, it is easy to cause local oxygen deficiency, resulting in suffocation of workers due to oxygen deficiency and posing a safety hazard to their lives. At the same time, it also reduces the arc extinguishing effect of high-voltage circuit breakers and causes damage to the circuit breaker body. Therefore, once SF6 gas leakage is discovered, corresponding measures must be taken to accurately locate the leakage point, repair the leakage point, and promptly eliminate the safety hazards of high-voltage circuit breakers.


The high-precision handheld SF6 gas leak detector accurately searches for SF6 gas leakage points through various methods such as detecting SF6 gas concentration values, providing sound and light alarms based on user set concentration thresholds, and detecting data trend charts, which brings convenience to SF6 equipment maintenance.
