Leak Tester

The leak tester detects sample leakage by pressurization or vacuum extraction, using the differential pressure method or bubble observation method to assess sealing performance. It is used for air tightness verification of products such as packaging containers and medical devices to prevent product failure due to medium leakage.
Selection
When selecting, consider matching the test pressure range with the sample's pressure-bearing capacity, equip corresponding fixtures based on the shape of the workpiece, and prioritize models with data recording capabilities. Soft packaging is suitable for positive pressure testing, while rigid containers can be tested using negative pressure methods.

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.
Negative Pressure Method Sealing Tester for Detecting Leakage in Food Packaging
The negative pressure method seal tester creates a pressure difference inside and outside the packaging by evacuating air to detect leaks in food packaging. If there is a leak in the packaging, water will enter the packaging or produce continuous bubbles under the pressure difference, thereby determining the seal integrity. The test requires controlling parameters such as vacuum level and time, and should be conducted in accordance with relevant standards.
Principle and Application of Vacuum Decay Leak Testing Equipment
The vacuum decay leak tester is a non-destructive detection device that quantitatively detects leaks by monitoring minute pressure changes in the test chamber after vacuum evacuation.
The rain test chamber simulates heavy rain environments to test the waterproof sealing performance of products.
A rain test chamber is a device that simulates rainfall environments, used to evaluate the waterproof performance of product casings or sealed components. It tests electronic products, automotive parts, and other items in accordance with relevant standards by controlling water flow, water pressure, and spray duration.
