    Spark Leak Detector

    Overview Knowledge Standards Terms
    Spark leak detectors utilize the principle of high-voltage discharge to apply an electric field on the surface of materials. When pinholes or defects are present, visible sparks are generated, which are used to detect the sealing integrity of materials such as plastic films and coatings. They are applied in industries like packaging and construction materials to ensure products are leak-free.
    Selection
    When selecting a spark leak detectors, consider the thickness and conductivity of the material to be tested to match the appropriate output voltage range. Choose between automatic or manual models based on the production line speed. Check the electrode type and sensitivity adjustment functions to ensure safe and reliable operation, meeting daily testing needs.

    Negative pressure method leak detector for testing vacuum packaging seal integrity
    The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
