Leak Tester

Product Information
MFY-01 Leak Tester is professionally designed for leak testing of food, medicine, medical instrument, daily used chemical product, auto part, electronic component, stationery and other various industrial product packaging. This device can also be used to test the sealing performance of samples after ball/weight drop and compression tests.

Test principle:
The pre-prepared sample is mounted between the lower and upper chambers under ambient atmospheric pressure. One of the chambers contains oxygen, and the other is filled with nitrogen by introducing a slow flow of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules pass through the sample and migrate towards the nitrogen side, and from there they go to the coulometer sensors, where they produce the relevant amount of electrical signal. The oxygen transmission rate is obtained by analyzing and calculating these signals. In packaged samples, high purity nitrogen flows into the package and oxygen flows out of the package.
