Leak Tester - QT-LT-V

Leak Tester - QT-LT-V (Negative Pressure Method)

ASTM D 3078

Leakage testing of pressurized packages is very important part of product manufacturing and preservation of product to maintaining its quality till consumption of product for industries which deal with food, beverages, pharmaceuticals, personal care etc.

Leakage Tester – QT-LT-V is used to test the hermetic sealing quality and performance of packaging bags, bottles, cans, etc.

It can also be used to test seal performance of specimens after compression tests, fall tests and other destructive testing methods.

Applications

QT-LT-V is used for determination of leakage and sealing efficiency of pressurized product package like cans, bags, bottles made from plastic, PVC, metal, glass, etc.

It can also be used to test packaging materials used for electronic components, medical instruments, pharmaceutical products, etc.

Features

• Automatic program controlled testing;
• Digital pre-set design of vacuum degree and vacuum retention time to ensure the accuracy of test data;
• Its auto testing feature complete control of test parameters like generation of vacuum, auto blow back, automatic stop and gathering test data with high precision and accuracy;
• Fast, easy and controlled operation.

Working Principle

The chamber enclosing the test package is evacuated and the negative pressure is stabilized for some time; after this stabilization time, the pressure change is observed in comparison to negative pressure to identify leakage rate.
