    Paint Leak Detection

    Overview Knowledge Standards Terms
    Paint leak detection is a method for identifying continuity defects in coatings. By applying voltage or fluorescent agents, changes in current at leak points or color reactions are observed to detect flaws such as pinholes and cracks, ensuring corrosion resistance and insulation performance.
    Selection
    When selecting a paint holiday detector, consider the coating type and thickness to match the detection voltage range; the operating environment determines whether a portable or fixed type is needed; examine the sensitivity and calibration methods to ensure accurate leak point identification; and refer to industry standards to verify the instrument's applicability.

    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.
