Airtightness testing equipment has been widely used in China since the 1990s, and has become a necessary equipment for testing industrial products.
The main application scenario of airtightness testing equipment is: to test the hermeticity of the tested object (finished product or semi-finished product), to ensure that the tested product does not have defects of water or air leakage.
Domestic and international airtightness test principle is basically the same, are compressed air as a medium, through the pressure drop method to detect the change of air pressure to calculate the product leakage, in order to determine whether the product meets the waterproof requirements.
Principle of airtightness test: pressure drop method
