    Leakage Detector

    Overview Knowledge Standards Terms
    A leak detector identifies leakage points by detecting pressure changes, bubble formation, or sensor signals generated during gas or liquid leaks. It is used for checking the sealing integrity of pipelines and containers, as well as locating leaks in chemical engineering and medical equipment maintenance.
    Selection
    Select gas or liquid leak detection type based on the medium being tested; match instrument sensitivity according to leakage requirements; consider ambient temperature and pressure ranges; check probe compatibility and portability needs; verify safety certifications and maintenance cycles.

    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.
