Labthink package leak testing apparatus MFY-01 Leak Tester is professionally applicable to the leakage tests of packages for food, drugs, medical instruments, daily chemical products, cars, electronic components, stationeries and other industrial products.
      
The instrument also could be used to the determination of seal performance of specimens after falling and compression tests.
    
Principle
Firstly submerge the specimen in the water within the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between inside and outside of the specimen. The leakage property could be obtained by observing the steady progression of bubbles from the specimen and how the specimen expands and restores to its original shape after vacuum release.

Professional Technolog
1. Digital preset design of vacuum degree and vacuum retention time to ensure the accuracy of test data
2. Specimens could be tested in the preset vacuum condition by automatic compensation of constant pressure
3. Professional software supports the functions of automatic back flushing and test termination to ensure smooth test process
4. Controlled by micro-computer, with LCD and PVC operation panel, which is convenient for customers to test and view test data
