Leak Tester LT-03

The vacuum leak tester can effectively evaluate the sealing process and sealing performance of flexible packaging parts, and provide scientific basis for determining relevant technical indicators. It can also help to ceck the sealing performance of the test piece after the drop and pressure test.

Test Principle

By vacuuming the vacuum chamber, a pressure difference is created between the inside and outside of the sample immersed in water.

A. The seal integrity of the sample is determined by observing the outward escape of gas bubbles or inward infiltration of water in the sample.

B. The seal integrity of the sample is observed the recovery of the sample shape after the sample expands and releases the vacuum.

Product Characteristics

Leak Tester LT-03 uses compressed air as the medium, to generates a stable vacuum through a vacuum ejector. The vaccum level is read through the a built-in high-precision pressure sensor. Parameter setting and test control are carried out through programmable logic controller (PLC), as well as the HMI(human-machine interface) touch screen.

The test parameters of test time duration and pressure can be saves in multiple groups, to save the parameter setting time for the same condition test.

Leak Tester LT-03 can automatically record the number of tests and test results(PASS/FAIL) at the same time.
