    Pressure Leak Detector

    Overview Knowledge Standards Terms
    The air pressure leak detector detects leaks by filling the test object with compressed air and monitoring pressure changes. It is used to identify leaks in seals, pipelines, or containers, ensuring product airtightness in the automotive, home appliance, and packaging industries.
    Selection
    When selecting a pneumatic leak detector, consider the test pressure range, accuracy, and response time to match the size of the test object and leakage standards. Evaluate environmental adaptability, ease of operation, and maintenance costs to ensure it meets practical detection 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.
