Test Principle
The instrument adopts the principle of differential pressure testing, placing the pre processed sample between the upper and lower testing chambers and clamping it. Firstly, evacuate the low-pressure chamber (lower chamber), and then evacuate the entire system; After reaching the specified vacuum degree, close the lower chamber of the test, fill the high-pressure chamber (upper chamber) with a certain pressure of test gas, and ensure that a constant pressure difference (adjustable) is formed on both sides of the sample; In this way, gas will permeate from the high-pressure side to the low-pressure side under the action of pressure gradient. By monitoring the increase in pressure in the low-pressure chamber, various barrier parameters of the tested sample can be obtained.
