Principle

C101H adopts the test principle of differential pressure method. The prepared sample is placed between the upper and lower test chambers and clamped. Vacuum the low-pressure chamber (lower chamber) and then vacuum the whole system. When achieving specified vacuum degree, close the lower chamber and fill the upper chamber (high-pressure chamber) with test gas at a certain pressure. Ensure a constant pressure difference (adjustable) is formed on both sides of the sample. The gas will permeate from the high-pressure side to the low-pressure side under the differential pressure gradient. Thus, by analyzing the internal pressure on the low-pressure side, the barrier parameters of the sample can be obtained.
