い。[Problem to be solved by the invention] In a method for detecting leakage of hydrogen sulfide gas from welds and connections in plants, machines, and equipment that handle hydrogen sulfide, a hydrogen sulfide gas detection tube detects leakage of hydrogen sulfide gas. However, it is difficult to find the leakage point. Furthermore, if a small amount of hydrogen sulfide gas leaks from pipes etc. that are open to the atmosphere, the hydrogen sulfide gas may be diluted into the atmosphere and the hydrogen sulfide gas may fall below the lower limit of determination. When there are many connection points and the measurement points are spread over a wide range, there is a problem as a leak detection means, and the leak point cannot be specified.
