Product Description

It adopts the test principle of negative pressure method and is suitable for the sealing test of bags, bottles, cans, boxes and other packages. The test can effectively compare and evaluate the sealing technology and sealing performance of the package, and provide a scientific basis for determining the relevant technical indicators. It can also be used to test the sealing performance of certain packages after drop and pressure tests. It is also called a sealing instrument, a sealing tester and a flexible packaging sealing tester.
 

Test principle

By evacuating the vacuum chamber, the sample immersed in water generates internal and external pressure difference, and observing the gas escape from the sample, so as to determine the sealing performance of the sample; by vacuuming the vacuum chamber, the sample generates internal and external pressure If it is poor, observe the sample shape recovery after the sample expands and releases the vacuum to determine the sealing performance of the sample.

Features

1. The key components are imported from world-renowned brands, with a measurement accuracy of 0.0001kPa and a vacuum accuracy of 0.01;
2. Imported high-speed and high-precision sampling chip to ensure the real-time and accuracy of test data;
3. Automatic constant pressure air supplement to ensure that the test can be carried out under the preset vacuum conditions;
4. The automatic back-blowing unloading function makes the process of the end of the test simple and smooth;
5. With gradient test mode, it is convenient to quickly find the critical value of sample leakage pressure;
6. Both vacuum degree and time can be preset, enter the value directly to enter the test mode;
7. 7-inch high-definition color LCD screen, convenient for users to control and display real-time data and curves;
8. Support historical data for quick viewing.
