A vacuum leak tester is a precision testing instrument used to identify leaks, seal defects, and packaging integrity issues in products and containers. It creates a controlled vacuum around the test sample and monitors pressure changes to detect leakage. Vacuum leak testers are widely used for flexible packaging, bottles, pouches, containers, and other sealed products. They help manufacturers maintain consistent quality, reduce product failures, and verify reliable sealing performance during quality control and production testing.
