What brand of air tightness tester is there in China with high accuracy?
The main application scenario of air tightness testing equipment is to test the air tightness of the tested object (finished product or semi-finished product) to ensure that there is no water leakage or air leakage defect in the tested product.
The principle of air tightness test at home and abroad is basically the same, which uses compressed air as the medium to calculate the leakage of products by detecting the change of air pressure by pressure drop method, so as to judge whether the products meet the waterproof requirements.
Principle of air tightness test: pressure drop method
