Work principle:
1.Use different pressure method .Put the prepared sample between
the upper and lower chamber ,clamping it.
2.Then do the vacuum for the whole system.
3.Close the lower testing chamber, input test gas in the upper
chamber, make sure form constant pressure between the two side of
test sample, for differential conditions, the gas will permeate
from the high pressure to lower pressure side, by monitoring the
pressure of the lower pressure side to get parameters of various
kinds testing samples.
