Circular vacuum leak detection cover/Michelo negative pressure leak detector

< Vacuum leak detector cover/Michelo negative pressure leak detector. . <# . Vacuum leak detector vacuum cover (round cover): plexiglass material diameter vacuum pump: absolute vacuum imported from Germany Application: used for geomembrane welding Other testing equipment for leak testing of seams and plastic tank welds: Peel force and tensile testing machines, test needles, spark microhole leak detectors, and air pressure tests on double welds. Seal both ends of the weld and insert pressure on one end to detect leaks. The needle then inflates air pressure into the cavity. If there is no change in pressure for a few minutes after inflation, the quality of the weld is qualified. If there are any changes, apply detection fluid. For local joints such as hole repairs, joints, etc., use vacuum detection.
