Test principle:
The host system is sealed and connected to a dedicated test chamber corresponding to the sample to be tested. The sample is placed in the test chamber, sealed, and then evacuated. This creates a pressure differential between the inside and outside of the sample, allowing gas to enter the test chamber and the host system through the leak. The host system uses the pressure change measured by the analysis sensor to calculate the sample's pressure decay value, equivalent pore diameter, standard flow rate, and other results, thereby determining whether the sample is leak-proof. The pressure decay method operates on the opposite principle.
