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.

1. 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.
Available Chambers
Cylinder shape of required height and
φ270mm, φ364mm, φ464mm, etc.
Cuboid shape with different LWH.
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 parameters saving function to improve
efficiency.
Other features includes
1. Strong and clear chamber provided, and different 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 modified to work with vacuum pump, to achieve higher vacuum

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.
