【Scope of application】 It is mainly suitable for the leakage sealing performance test of packaging bags, bottles, tubes, cans, boxes, etc. in food, medicine, medical devices, daily chemicals, automobiles, electronic components, stationery, pesticides, veterinary drugs and other industries to test the integrity of the packaging, and judge whether there is a leakage problem in the packaging through the test. This test can ensure the integrity of the entire product packaging seal and prevent leakage, contamination, deterioration and other problems caused by poor product sealing performance. 【Relevant Standards】

GB/T 15171、ASTM D3078、GB/T 27728

Standard RS232 data communication interface, convenient for data export and external connection; 【Test Principle】: By vacuuming the vacuum chamber, the internal and external pressure difference occurs in the sample immersed in water, and the gas escape in the test sample is observed to determine the sealing performance of the sample. The sealing performance of the specimen can also be determined by vacuuming the vacuum chamber to produce the pressure difference between the inside and outside the specimen, and observe the shape recovery of the specimen and the liquid infiltration after the specimen expands and releases the vacuum. [Equipment configuration]: Standard configuration: main unit, vacuum chamber Note: Users bring their own gas source
