Influence factors of permeability test
There are many factors affecting the permeability test, such as the precision of the sensor, the effective range, the system leakage, the sample processing, the material characteristic, the test environment, the hardware design, the software processing and so on. Many of these factors are decided by congenital design, from the perspective of application, the user is not concerned with the manufacturer is how to improve these conditions, but to what, after what conditions, in order to obtain accurate test data, this paper introduces two main indicators: blank test and test the results of repeatability.
Two, blank test data
