    Leakage Testing Instrument

    Overview Knowledge Standards Terms
    Leak detection testers detect leaks in seals by monitoring pressure changes or using gas tracers. The instrument injects gas into the test object and monitors pressure decay or uses sensors to capture escaping gas. It is used to verify the tightness of pipelines and containers, ensuring the safe operation of equipment.
    Selection
    When selecting a leak detector, it is essential to match the detection accuracy with the operational pressure range. Consider the compatibility of the testing medium, and pay attention to response speed and data recording capabilities. Choose appropriate fixtures based on the size of the object being tested, and verify the instrument's calibration cycle and maintenance costs.

    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.
