High Precision Leak Tester Supplier From China

Item: LEAK-01
Vacuum Degree: 0~ -90kPa
Accuracy: 0.1%FS
Test Method: Two detection methods

Brief Introduction 

LEAK-01 Leak Tester, using negative pressure method, is designed for the leakage tests of packaging bags, bottles, cans, boxes and other packaging materials. Through leak tests, the sealing processing and seal performance of the packages can be determined properly and the test results may be used for reference when determining other technical parameters. The instrument also can be used to test seal performance of specimens after falling and compression tests. 

Technical Features

- Negative pressure method, vacuum degree can be set and controlled 

- 7 inch HD LCD, displaying test data and curves in real time

- The vacuum degree can be set by range to avoid the parameter resetting in multiple tests.

- Embedded micro-computer chips, simplified and efficient user interface provide users with comfortable and smooth operating experience

- Imported high-speed and high-precision chips guarantee the testing accuracy and efficiency

- Specimens could be tested in the preset vacuum condition by automatic compensation of constant pressure

- Automatic back flushing function simplifies the testing process

- Overvoltage protection ensures the operating safety

- Both vacuum degree and time can be preset, enter the value directly to enter the test mode

- With a powerful data storage function, which can store up to 50,000 test records

- The result is automatically determined, and the test data can be printed

- Support historical data for quick viewing and printing

- Standard, modularized and systematic designs can meet personalized requirements of the users

- Well-designed user interface for touch screen operations

- Key components and parts are supplied by world-brand manufacturers, which guarantee the stable and reliable performance of the instrument.

- Low energy consumption makes the instrument environment-friendly

- Equipped with standard RS232 interface, which is convenient to PC connection and data transmission

Test Principle

The specimen is submerged in the water within the vacuum chamber, and then the vacuum chamber is evacuated to form a pressure difference between the inside and outside of specimen. The seal performance can be obtained by observing whether there are steady progression of bubbles from the specimen and how the specimen expands and restores to its original shape after vacuum release.


Basic Applications
Flexible packages
Cans, bottles, pipes and boxes
Paper plastic composite bags and boxes
Packages after falling and compression tests
