    Universal Leak Detector

    Overview Knowledge Standards Terms
    Universal leak detectors identify leaks by sensing physical signal changes caused by gas or liquid leakage, such as pressure differentials, acoustic waves, or bubble formation. They are commonly used to locate leaks in pipelines, containers, and sealing points during equipment maintenance and safety inspections.
    Selection
    When selecting, consider matching the sensor type to the characteristics of the detection medium, clarify the sensitivity range and response speed requirements, verify environmental interference resistance, confirm device portability and operational complexity, and evaluate maintenance costs in conjunction with the budget.

    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.
