The airtightness tester is a gas tightness tester that uses compressed air as a test medium. It is a testing instrument for waterproof testing and sealing test. It has the characteristics of non-destructive, fast and stable. The principle of air tightness detector: the pressure change inside or outside the channel detection product, and the leakage value per unit time is calculated. The airtightness of the product to be tested is determined based on the leak value.

Xili was invited to visit Meizu to explore the airtightness detector technology, which is applied to the application field of mobile phone online waterproof detection and mobile phone accessories waterproof test.
