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 parameters saving function to improve efficiency.
