How to check the gas tightness of the measuring tube device

At present, the general use of airtightness tester to detect, the main principle is differential pressure detection, at the same time need to be based on the product to be tested to produce a set of tooling.

The specific detection method needs to be based on the performance of the product under test, volume and other parameters to choose the appropriate detection pressure and detection time.

You can also consult the air leak detector manufacturers, explain what you want to test, most of them are more professional to give you a more complete program.

At present, the better quality of the leak detector brands are France ATEQ, Japan cosmos, domestic Shenyang Eltek, Tianjin Fuko and so on.
