Brief introduction
Suitable for sealing test food , drugs, cosmetics , industrial products such as flexible packaging, bottle packaging, packaging materials such as barrels , MFY-05 negative pressure test mode , automatic chronograph automatic replenishment vacuum packaging are fully automated high-precision inspection drain devices. Sealing process and sealing performance can be effectively tested and evaluated by comparing the flexible parts , widely used in food , plastic flexible packaging, wet wipes , pharmaceutical , cosmetic and other industries tightness testing .

Features
1. Microcomputer control digital display test vacuum degree
2. Digital preset test the degree of vacuum and vacuum hold time , to ensure the accuracy of the test data
3. The use of high quality system components, stable and reliable performance
4. Automatic constant qi further ensure that the test can be carried out under vacuum conditions preset
5. Automatic constant pressure gas
6. Automatic end of the trial
7. Automatic cleaning uninstall

Test Principle
Through the vacuum chamber is evacuated , so that the sample immersed in water to generate external pressure , observing the sample gas to escape , as a means to determine the sealing properties of the specimen ; may be evacuated by the vacuum chamber , the sample to produce internal and external pressure , swelling and release the sample specimen shape recovery after vacuum infiltration and liquid observation , as a means to determine the sealing properties of the sample .
