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.

Summary: The product features, advantages and representative products of these brands are different. Users can choose their own air tightness detector according to their own needs and application scenarios. If the budget is sufficient, you can consider importing leak detectors. If the budget is limited, it is also a good choice to replace it with domestic air tightness testing equipment.
