Test Description & Method

Vacuum Leak Test Method – Reliable and Precise Testing

The Vacuum Leak Test performed by the LT-03 Leak Tester involves placing the sample in a water-filled acrylic chamber. Once the chamber is sealed, the control unit applies a vacuum up to -90 KPa, as specified by the user. If there is a minor leak, the pressure difference forces air out of the packaging, visible as bubbles in the water. This method is ideal for detecting even small leaks, ensuring packaging integrity.

Key Technical Specifications

Test Range	0~-90 KPa
Chamber	Acrylic Cylinder Shape
Test Space	Φ270*H210mm (Inside Usable)
Compressed Air	0.7MPa (prepared by user)
Power	110~220V 50/60Hz

Additional Features

PLC-Controlled with HMI Touchscreen

The LT-03 Leak Tester comes equipped with an advanced PLC (Programmable Logic Controller) system, ensuring industrial-level reliability and stability. The HMI (Human-Machine Interface) touchscreen offers an intuitive and user-friendly interface, allowing operators to easily set test parameters, monitor real-time data, and control the testing process with precision. This advanced system reduces human error, streamlines operations, and ensures consistent, repeatable results, making it ideal for high-demand environments.

Venturi Tube for Stable Vacuum Generation

The LT-03 utilizes a Venturi tube vacuum generation system, which offers several advantages over traditional mechanical pumps. This technology allows for the efficient creation of a stable vacuum without the need for moving parts, reducing maintenance needs and ensuring a vacuum level of up to -90 KPa. The Venturi system is not only cost-effective but also ideal for industries where reliable vacuum generation is crucial for accurate leak testing. Its efficient design simplifies the process, making it easier for operators to achieve consistent results across multiple tests.

Parameter-Saving Function for Up to 5 Groups

To enhance workflow efficiency, the LT-03 offers a parameter-saving function that allows users to store settings for up to five distinct test groups. This feature is particularly beneficial for operators who handle a wide variety of sample types and test conditions. By saving critical parameters such as vacuum levels and test durations, the system minimizes setup time and enables quick transitions between different testing protocols, ensuring faster throughput and improved productivity in the lab or production line.

Optional Micro-Printer and Local Language Display Support

For added convenience and traceability, the LT-03 can be fitted with an optional micro-printer. This feature allows operators to print real-time test data, such as test results and sample identification, directly after testing. This enhances record-keeping and ensures accurate documentation for quality control and auditing purposes. Additionally, the system offers local language display support, allowing the interface to be customized in various languages. This makes the LT-03 suitable for global operations, ensuring accessibility and ease of use for operators worldwide.

Frequently Asked Questions

What is the difference between vacuum leak testing and pressure decay testing?

Vacuum Leak Testing involves creating a vacuum inside a test chamber that contains the package. The test observes the chamber for air bubbles that emerge from any leaks, indicating compromised seals. This method is especially effective for flexible packaging.
Pressure Decay Testing, on the other hand, uses positive pressure within the package or the test chamber. The test monitors pressure drop over time; a decrease indicates a leak. Pressure decay is often more suitable for rigid or semi-rigid packages.

How does the LT-03 comply with ASTM D3078 standards for flexible packaging?

The LT-03 Leak Tester complies with ASTM D3078 by utilizing the vacuum method to assess the integrity of flexible packaging. It specifically meets the standard’s requirements for detecting leaks through a water-submersion method, ensuring that packages are capable of providing the required protection against contamination and product spoilage.

Can the LT-03 be used for non-flexible materials or rigid packaging?

Yes, the LT-03 can also be adapted for use with non-flexible materials and rigid packaging. While it is primarily designed for flexible packaging, the customizable chamber shapes and sizes allow it to accommodate various packaging types, including rigid containers, provided the test method is appropriate for the material.

How can the parameter-saving function improve test efficiency for varying samples?

The parameter-saving function of the LT-03 allows operators to store settings for up to five different test groups, each with its unique parameters such as vacuum levels and test durations. This capability significantly reduces setup time, enabling quicker transitions between tests for different sample types, thus improving overall test efficiency and throughput.

What are the benefits of using a Venturi tube for vacuum generation compared to other methods?

The use of a Venturi tube for vacuum generation offers several benefits, including:
Stability: The Venturi design provides a consistent vacuum level, essential for reliable leak detection.
Cost-effectiveness: It requires less energy compared to traditional vacuum pumps, lowering operational costs.
Simplicity: The system is easier to operate and requires less technical knowledge to maintain.

Can the LT-03 detect micro-leaks that are not visible to the naked eye?

Yes, the LT-03 is capable of detecting micro-leaks that may not be visible to the naked eye but the leak has to create bubbles. By monitoring the vacuum levels and observing bubble formation during the testing process, the system can identify even the smallest leaks, ensuring comprehensive package integrity assessment.

How does the optional micro-printer enhance sample traceability in batch testing?

The optional micro-printer allows for immediate printing of test results, including sample identification, date, and other critical data. This feature enhances traceability by providing physical records for batch testing, which are essential for quality control and regulatory compliance in manufacturing processes.

How do the test space dimensions accommodate different package sizes?

The LT-03 features a flexible design with customizable test space dimensions, including cylinder and cuboid shapes. The available dimensions (e.g., Φ270*H210mm) can accommodate a range of package sizes and shapes, making it suitable for various applications in packaging testing. This adaptability ensures that users can conduct reliable leak tests on diverse packaging formats.
