Product Description

LEAK-01 Vacuum sealing performance tester with bubble emission method
LEAK-01 Vacuum sealing performance tester with bubble emission method, using negative pressure method, is applicable to leak detection of packaging bags, bottles, cans and boxes, etc. Through leak tests, the sealing processing and seal 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.

• Automatic blowback and unloading function, making the end of the test process simple and smooth
• Safety design such as over-voltage safety protection and power-down memory ensure the stability of the system during the test
• Equipped with standard RS232 interface, which is convenient to PC connection and data transmission
• Low energy consumption makes the instrument environment-friendly

Originality design

• 7" HD LCD, displaying test data and curves in real time
• With gradient test mode, which is convenient to find the critical value of sample leakage pressure quickly
• Vacuum degree and time can be preset, input the value can 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
• Based on the flat design concept, a new design of the UI interface has been carried out to bring users a more concise, efficient and comfortable operating experience

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.
