Vacuum Decay Leak Detection Tester to detect various packaging containers Introduction AUTO GBM-L1 Vacuum Decay Leak Detection Tester adopts the principle of vacuum decay to detect micro-leakage of finished packaging. The tester is suitable for micro-leakage detection and integrity leak detection of various packaging containers. It can be applied to leak detection of pharmaceutical packaging, food packaging, and chemical industry packaging such as vials, ampoules, HDPE bottles, and prefilled needles. The seal tester has the advantages of non-destructive, non-destructive, and no need for sample preparation. Test principle Based on dual sensor technology, vacuum decay method principle of dual circulation system. Connect the main unit of the microleak leak tester to a test chamber specially designed to hold the package to be tested. The instrument vacuumizes the test chamber, and a pressure difference is formed inside and outside the package. Under the action of pressure, the gas in the package diffuses into the test chamber through the leak hole. The dual-sensor technology detects the relationship between time and pressure, and compares it with the standard value. Determine whether the sample leaks.
