Pinhole leak detection

Pinhole leak detection involves applying pressure or vacuum to identify tiny holes on the surface of coatings or films. Gas or liquid escapes from defects, forming bubbles or causing a pressure drop, thereby verifying the sealing integrity of materials. This method is used for leak-proof testing in packaging, pipelines, containers, and more.
Selection
When selecting pinhole leak detection, it is necessary to match material thickness and detection sensitivity, consider the compatibility of the test pressure range with sample size, and pay attention to equipment stability and ease of operation. Verify the instrument's accuracy according to industry standards and ensure the testing environment complies with safety regulations.
