Micro-leakage Sealing Tester

Micro-leak Sealing Tester Leak-S is suitable for package sealing test. The instrument adopts the principle of vacuum attenuation testing and completely non-destructive testing technology, which meets the ASTM testing method. High precision testing techniques can detect leaks in micro holes.

Principle of Vacuum Attenuation Test

According to ASTM F2338 vacuum attenuation sealing test standard requirements, Based on dual sensing technology, dual cycle testing system. The specific testing process involves connecting the main unit of the micro leakage sealing tester to a specially designed testing chamber to accommodate the object to be tested. The instrument evacuates the testing chamber, creating a pressure difference between the inside and outside of the packaging. Under the pressure, the gas inside the packaging diffuses into the testing chamber through the leakage hole. The dual sensor technology detects the relationship between time and pressure changes and compares it with the standard value (established mathematical model) to determine whether the sample is leaking.

Technical Characteristics

1. Corresponding test chambers can be selected for different detection samples, and users can easily replace them, minimizing user expenses while meeting the needs of more types of samples

2. It has good detection adaptability and is suitable for detecting small leaks. It can also identify samples with large leaks and provide a judgment of qualified and unqualified

3. Non destructive testing methods are used to detect leaks in packaging . After testing, the samples are undamaged and do not affect normal use. The testing cost is low, and the test results are non subjective and do not require manual participation, ensuring data accuracy and objectivity

4. Adopting imported top brand vacuum pneumatic components to ensure high testing accuracy

5. Password protection function can be enabled, divided into four levels of permission management. Each operator has a unique login name and password combination to enter the instrument operation

6. A comprehensive audit tracking system that meets FDA 21CFR PART11 electronic record and electronic signature requirements

Local data storage, automatic processing, and statistical testing data functions.
