The Vacuum Leak Tester from Pacorr are designed to detect even the smallest leaks and defects in packaging by creating a controlled vacuum environment. If a leak is present, the change in vacuum level will indicate a defect. This method of testing is non-destructive, allowing the tested packages to be used or sold after testing, making it an efficient and cost-effective solution for quality control​​.

Pacorr offers both digital and wet testing models of Vacuum Leak Tester. The digital model is equipped with features such as a wide range of vacuum levels, a large space for testing different sized packaging materials, a Polycarbonate desiccator, and a vacuum pump. It also includes an LCD display with backlight, soft-touch keys, and a printer facility upon request. The machine's design focuses on precision and ease of use, with programmable controls for vacuum pressure and hold time, ensuring accurate detection of leaks​​.

The wet testing model, on the other hand, emphasizes the detection of leaks through a method that involves immersing the packaging material in a liquid solution. This model is suitable for a variety of packaging types and sizes, featuring an acrylic chamber for visibility, an analogue gauge for vacuum checking, and a built-in pressure control system for accurate pressure delivery during tests. It also includes features for automated calibration, high-strength clamping, and memory space to store up to 9 test values​​.

Both models offer precision, efficiency, and flexibility, catering to a broad range of packaging testing needs and complying with industry standards and regulations. By employing such advanced testing solutions, businesses can significantly enhance their quality control processes, reduce product waste, and ensure customer satisfaction with high-quality, safe products.

What is a Vacuum Leak Tester?

The Vacuum Leak Tester is an advanced device designed to detect leaks in packaging without damaging the product. It works by creating a vacuum environment around the package, then monitoring for any changes in pressure that indicate a leak. This method is crucial for ensuring product safety and shelf life, especially in industries where contamination can lead to serious health risks.

How does the Vacuum Leak Tester work?

To use the Vacuum Leak Tester, the package is placed inside a vacuum chamber, and air is removed to create a vacuum. The device then measures the rate at which the vacuum pressure returns to normal. If the pressure normalizes too quickly, it indicates the presence of a leak. The tester provides precise measurements, allowing for quantitative analysis of leak severity.

What types of packages can be tested?

The Vacuum Leak Tester is versatile and can be used on a wide range of packaging types, including blister packs, bottles, cans, and pouches. It's suitable for various materials like plastic, glass, and metal, making it an essential tool for numerous industries.

How do I maintain my Vacuum Leak Tester?

Maintenance is key to ensuring your Vacuum Leak Tester remains accurate and reliable. Regularly check the vacuum chamber and seals for any signs of wear or damage. Keep the device clean, especially the chamber, to avoid any false readings. Calibration should be performed periodically, as recommended by the manufacturer, to ensure measurement accuracy.

Can the Vacuum Leak Tester detect micro leaks?

Yes, the Vacuum Leak Tester is capable of detecting micro leaks thanks to its sensitive pressure sensors and precise vacuum control. It can identify even the smallest leaks that might not be visible to the naked eye, ensuring the integrity of your packaging.

What should I do if my Vacuum Leak Tester gives inconsistent results?

Inconsistent results can occur due to several reasons. First, ensure that the packages you're testing are correctly placed and sealed within the chamber. Check the device for any signs of damage or malfunction. It's also a good idea to recalibrate the tester to confirm its accuracy. If issues persist, contact the manufacturer or a professional technician for further assistance.

Conclusion

The Vacuum Leak Tester is a critical device for maintaining the highest packaging standards, ensuring product safety, and extending shelf life. By understanding how to effectively use and maintain this equipment, you can significantly enhance your quality control processes.
