Leak Tester LT-02

LT-02 leak tester is the first generation automatic vacuum tester introduced by Cell Instruments. The ASTM D3078 is the standard test method for determination of gross leaks in flexible packaging containing a headspace gas by bubble emission. The test is conducted by submerging the test specimen in the immersion fluid within the confines of a vacuum chamber.

How the vacuum leak tester is performed? 

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.

 

 

Technical features

Leak tester LT-02 uses compressed air as the power source to generate a stable vacuum degree through a vacuum generator. Control and display pressure by precision SMC vacuum pressure switch and timer. 

  • Digital vacuum degree and test time setting; test process automatic
  • utomatic vacuum maintenance and air back-flushing
  • Cast type PMMA vacuum chamber, better for food and pharmaceutical testing
  • We offer different chamber size
  • Use compressed air to convert to vacuum. No vacuum pump required
  • Easy operation and maintenance
