The industrial testing process is one of the last and most important stages involving products before their launch by the manufacturer.
This is why it’s essential for whoever is in charge of quality control to have efficient and accurate equipment to make sure products function correctly and avoid any waste of time caused by measuring errors.
In the case of tools for air tightness testing, checks to verify the correctness of the testing programme parameters used is normally carried out with the aid of two accessories, calibrated leak devices or leak calibrators.
Calibrated leak devices are used to simulate the maximum leakage value of the tested part, allowing to set up the correct testing programme and the following periodical tests.
This type of device has the advantage of being immediate, as all it requires is to be connected to the testing instrument connected to the specific part that requires testing and it work without any external intervention.
The only limit is that it has a single fixed leak and pressure value that cannot be changed.
To overcome this problem, the solution is to use leak calibrators, which can check a wider functioning range.
