Application: Ensuring the integrity of package seals is paramount in guaranteeing product protection. Seal integrity assessments are pivotal in evaluating sustainable packaging alternatives, cost-effective packaging solutions, and variations in production line sealing parameters. Preserving the reliability of package seals is indispensable for upholding product quality and safety.

Test Description: The LT-03 Leak Tester facilitates comprehensive assessment of package seal integrity. The sample is immersed in a water-filled chamber and securely covered. Subsequently, the control unit initiates air extraction until reaching the pre-set vacuum level. In the presence of a minor leak, the pressure difference expels trapped air, visibly manifesting as bubbles emerging from the leak area.

Technical Features:

1. PLC-controlled unit ensures industrial-level stability, complemented by intuitive HMI touch screen operation.
2. Utilizes a Venturi tube to attain a stable vacuum of up to -90KPa, considering the practicality of acquiring compressed air.
3. The testing methodology relies on visual observation, providing cumulative result numbers, rather than direct Pass/Fail outcomes.
4. Features a parameter-saving function accommodating 5 groups, enhancing efficiency for users with diverse samples and test conditions, including vacuum level and test duration.

Additional Features: 5) Equipped with a robust and transparent chamber, customizable to accommodate various sizes and shapes of samples.

6. Offers optional integration of a micro printer for convenient sample identification.
7. Optionally adaptable for display in local languages, facilitating ease of use across different regions.
8. Modifiable to interface with a vacuum pump, enabling operation at higher vacuum levels.
