LT-03 Leak Tester

Application

Testing the integrity of package seals helps ensure that the packaging provides required

product protection. Sustainable packaging alternatives, lower cost packaging, and variations

in production line sealing parameters are frequently assessed with seal integrity tests.

Maintaining the reliability of package seals is critical for product quality and safety.

 

Various ways of leak test

Standards	Method	Used For	Our Solution
ASTM D3078	Bubble emission	MAP,pack with air, liquid filled	LT-01, LT-02, LT-03
ASTM D4991	Bubble emission	Empty Rigid Containers	LT-01, LT-02, LT-03 modified
ASTM F2096	Internal Pressurizatio	Gross Leaks	GLT-01
ASTM F2338	Vacuum decay	Flexible pack, rigid containers	MLT-01
ASTM F2054 ASTM F1140	Pressure decay	Flexible, rigid, tube, etc	LSST-01

Test Description

A sample is placed into the chamber filled with water. After the lid is put back.

the control unit start to extract the air inside chamber out, until the preset vacuum

is achieved. Because of the pressure difference between inside and outside of sample, air in it will

escape if there is a small leak. The leak is shown by a stream of bubbles from the leak area.

Technical Features

☛PLC controlled unit(industrial level stable) and HMI touch screen operated.

☛To achieve stable vacuum and considering the fact that compressed air is

easier to be obtained at user facility, we use Venturi tube for a high level of

vacuum up to –90KPa.

☛This way of test is based on eye observation, which means the tester

doesn’t give a direct result of whether a sample Passes or Fails. By “telling”

tester the sample status, it automatically accumulates the result numbers.

☛For user having various types of samples and test conditions(vacuum level

and test time), LT-03 has 5 group parameter saving funciton to improve

efficiency.

Other features includes

1. Strong and clear chamber provided, and diffferent sizes and shapes could be customized

2. A microprinter could be added for user to distinguish sample(optional)

3. It could be modified to local language display(optional)

4. It could be modifed to work with vacuum pump, to achieve higher vacuum
