Leak Tester (Vacuum Method)

Leak Tester is designed for the examination of airproof property of packages, containers, bags,pipes. Leak tester is widely used in food, beverage, pharmaceutical, daily chemical, electrical and electronic industries, etc.

Leak Tester (Vacuum Method)

Leak Tester complies with ASTM D3078 “Test Method for Determination of Leaks in Flexible Packag-ing by Bubble Emission”

Principle

A test sample is placed into a vacuum chamber with water and the air above water is evacuated by a venturi tube. 

A pressure difference is created inside and outside the sample and leakage can be observed and identified when the sample is inflated and a stream of bubbles appeared.

Methylene blue test

1. The blister is in chamber with solution (Methylene Blue) 

2. Vent the chamber and hold the vacuum for a while 

3. Stop the vacuum and hold blister in normal pressure. The dye will enter the blister if there is leak.

LT-03 Leak Tester uses vacuum ejector to generate stable vacuum environment. The state-of-the-art human-computer interface and PLC control unit on the leak tester make the parameter setting and test operation direct and easy.

1. Leak test process all automatic

2. Touching screen operation

3. Digital vacuum degree and test time input
