Vacuum Leak Tester

I. Product Overview

The Sealing Tester (also known as the negative-pressure sealing tester) is suitable for the sealing test of flexible packages such as bags, bottles, tubes, cans and boxes in the food, pharmaceutical, medical device, daily chemical, automotive, electronic component and stationery industries. Through the test, the sealing process and sealing performance of flexible packages can be effectively compared and evaluated, providing a scientific basis for determining the relevant technical indicators; it can also be used to test the sealing performance of specimens after drop tests and compression tests.

II. Product Features

1. Self-developed Linux operating system with a 7-inch touch screen and one-key operation, making the interface more convenient and intuitive;

2. Automatic constant-pressure air replenishment further ensures that the test can be carried out under the preset vacuum conditions; vacuum pumping, pressure holding, pressure replenishment, timing, blowback, storage and printing are all fully automated with one-key operation;

3. Supports both normal and gradient dual test modes for multiple choices and higher testing efficiency;

4. Supports manual switching between Chinese and English to meet different language requirements;

5. Globally applicable test units (kPa and mbar) can be switched freely;

6. Real-time display of the test pressure curve for quick review of test results;

7. The system adopts digital presetting of the test vacuum degree and the vacuum holding time to ensure the accuracy of test data;

8. Uses world-renowned SMC imported pneumatic components for stable and reliable performance;

9. Automatic storage of test data to prevent data loss;

10. Wi-Fi connection function; the device supports remote OTA upgrade and maintenance;

11. Built-in storage of 10,000 records; stored data can be selected for printing, with dual retrieval by time and user name, meeting the needs of large data volumes;

12. Built-in micro printer and USB universal data interface for convenient data output and transfer;

13. Lightweight design for convenient relocation of testing sites.

III. Testing Principle

This product adopts the negative-pressure testing principle. By evacuating the vacuum chamber, a pressure difference is created between the inside and outside of the specimen immersed in water, and the escape of gas from the specimen is observed to judge the sealing performance of the specimen; alternatively, by evacuating the vacuum chamber, a pressure difference is created across the specimen, and the expansion of the specimen as well as its shape recovery after the vacuum is released is observed to judge the sealing performance of the specimen.

IV. Executive Standards

This instrument complies with a number of national and international standards: GB/T 15171, ASTM D3078, GB/T 27728, YBB 00112002-2015, YBB 00122002-2015, YBB 00262002-2015, YBB 0005-2015, YBB 00092002-2015 and YBB 00392003-2015.
