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 sealing of the object to be tested (finished or semi-finished products), to ensure that there is no leakage of water or air leakage defects in the product to be tested.
Domestic and foreign airtightness test principle is basically similar, are compressed air as a medium, through the pressure drop method to detect changes in air pressure to calculate the product leakage, in order to determine whether the product meets the waterproof requirements.
