GB/T 15171 Digital Display Negative Pressure Seal Tester

Model: MFY-01

Purpose: Suitable for seal testing of packaging bags, bottles, tubes, cans, boxes, etc., in industries such as food, pharmaceuticals, medical devices, daily chemicals, automotive, electronic components, and stationery. It can also be used to test the sealing performance of specimens after drop and pressure resistance tests.

Test Principle: By evacuating the vacuum chamber, a pressure difference is created inside and outside the specimen immersed in water, and the escape of gas from the specimen is observed to determine its sealing performance. Alternatively, by evacuating the vacuum chamber to create a pressure difference, the expansion of the specimen and its recovery after vacuum release are observed to assess sealing performance.
