Vacuum leak tester GB-M3

packaging

Product profile GB-M3 leakage tester with high precision electronic pressure sensor as measuring means, through microcomputer control, in a test process can complete the vacuum negative pressure, compressed air pressure and positive and negative pressure cycle test, effectively compare and evaluate the sealing process and sealing performance of soft packaging, to provide scientific basis for determining the relevant technical requirements. Suitable for food, pharmaceutical, daily chemical and other industries of soft packaging parts sealing performance test. Principle The sealing performance of the sample is determined by vacuum the sealed bucket or pressurizing the compressed air for the internal and external pressure difference, and observing the gas escape of the sample or water infiltration to the inside of the sample. Standard ASTM D3078, ASTM F2096
