    Leak Detector

    Overview Knowledge Terms
    Leak detectors use principles of pressure decay or vacuum testing to detect tiny leaks in packaging materials, containers, or pipelines. They fill the test object with gas, monitor pressure changes to assess sealing integrity, and are used for quality inspection in food packaging, medical devices, and industrial containers.
    Selection
    When selecting a leak detector, consider the material and shape of the test object, match the testing pressure range and accuracy requirements. Determine whether a manual or automatic model is needed based on the production environment, verify detection sensitivity according to industry standards, and ensure the device is compatible with existing production line processes.

    Negative Pressure Method Sealing Tester for Detecting Leakage in Food Packaging
    The negative pressure method seal tester creates a pressure difference inside and outside the packaging by evacuating air to detect leaks in food packaging. If there is a leak in the packaging, water will enter the packaging or produce continuous bubbles under the pressure difference, thereby determining the seal integrity. The test requires controlling parameters such as vacuum level and time, and should be conducted in accordance with relevant standards.
