Labtron Plastic Testing Instruments has a microprocessor-controlled PID system that ensures precise temperature balance for consistent results. These include an inside chamber constructed from durable stainless steel, offering long-lasting reliability. Their test samples retain their physical properties even after aging, ensuring accurate assessments. They have adopted a double-pipe structure for enhanced durability and performance. Our plastic testing instruments effectively determine the anti-impact properties of materials, providing valuable data for material testing and quality control.








Our Vacuum Leak Tester operates by creating a controlled vacuum environment within a sealed chamber where the product under test is placed. It employs a high-precision pressure sensor to monitor the intake pressure in real time, ensuring the vacuum degree, which ranges from 0 to 95 kPa with an accuracy of ± 1%, is accurately maintained. The testing process is automated, with the device managing adjustable hold times from 0.1 to 60 minutes, and automatically performing functions such as stopping the test and executing a back-blow to re-establish ambient conditions, ensuring consistent and repeatable results.
This Vacuum Leak Tester offers several features aimed at delivering precise and reliable leak detection. It includes a high-precision pressure sensor for real-time monitoring, an intuitive touchscreen interface for easy operation and data management, and an automated testing process that minimizes human error by controlling vacuum generation, test execution, stopping, and back-blow functions. Additionally, the tester provides customizable vacuum tank dimensions (standard size Ø 300 × 350 mm) to accommodate various product sizes, ensuring it can be tailored to meet diverse testing needs.
The Vacuum Leak Tester is highly beneficial in industries that require secure and high-quality packaging. In the food industry, it ensures that perishable products remain properly sealed, thereby extending shelf life and preventing contamination. The pharmaceutical sector relies on it to guarantee that medications and medical supplies maintain their efficacy and safety by being leak-free. Moreover, industries dealing with daily chemicals, including cleaning agents and personal care products, also use this tester to uphold stringent packaging standards, making it an essential tool across multiple sectors.
Regular maintenance and calibration are essential for ensuring optimal performance and longevity of the Vacuum Leak Tester. Users should adhere to the manufacturer’s maintenance guidelines, which typically include routine cleaning of the vacuum chamber and sensor components to prevent any contamination or blockages. Calibration should be performed periodically to ensure that the pressure sensor remains accurate, maintaining the vacuum conditions within specified tolerances. Additionally, keeping the device’s software updated can enhance its performance and functionality. These practices help guarantee consistent, reliable test results, thereby ensuring ongoing product quality and compliance with industry standards.
Yes, one of the major advantages of our Vacuum Leak Tester is its adaptability for various testing requirements. Users can customize several key parameters, including the vacuum degree, hold times, and even the dimensions of the vacuum tank—standard at Ø 300 × 350 mm but adjustable as needed. This flexibility allows the device to be fine-tuned for a wide range of packaging materials and industry specifications, ensuring accurate leak detection even under diverse testing scenarios. This level of customization makes the tester a versatile solution suitable for both high-speed production environments and specialized quality control processes.
