Mainly used for leak detection of SF6 high-voltage GIS, insulators, crank arm chamberes,shells, aluminum castings and other products. The inspected workpiece has a relatively largeexternal size and high helium filling pressure. The vacuum chamber type detection of overallleakage rate or the suction gun method for detecting leakage points are commonly used in the
industry.
