Vacuum Leak Tester

Product Introduction

The Seal Tester (also known as the negative-pressure seal tester) is suitable for the seal test of flexible packages such as bags, bottles, tubes, cans and boxes in the food, pharmaceutical, medical device, daily chemical, automotive, electronic component and stationery industries. Through the test, the sealing process and sealing performance of flexible packages can be effectively compared and evaluated, providing a scientific basis for determining relevant technical indicators, and the sealing performance of specimens after drop and pressure resistance tests can also be tested.

Product Features

• Self-developed Linux software operating system, 7-inch touch screen, one-key operation, more convenient and intuitive operation interface.
• Automatic constant-pressure air replenishment, further ensuring that the test can be carried out under the preset vacuum conditions; vacuum pumping, pressure holding, pressure replenishment, timing, blowback, storage and printing are fully automated with one-key operation.
• Supports both normal and gradient dual test modes, with multiple choices to improve test efficiency.
• Supports manual switching between Chinese and English, meeting different language requirements.
• Global general test units (kPa and mbar) can be switched freely.
• Real-time display of the test pressure curve, convenient for quickly checking the test results.
• The system uses digital presetting of the test vacuum degree and vacuum holding time, ensuring the accuracy of test data.
• Adopts world-renowned SMC imported pneumatic components, with stable and reliable performance.
• Four-level user authority management with password login, convenient for device management.
• Has an audit trail function, tracking and recording various activities occurring in the information system, complying with the data traceability requirements of China GMP; all operation records can be printed out.
• Has an automatic test data storage function to prevent data loss.
• Has a WiFi connection function; the device supports remote OTA upgrade and maintenance.
• Built-in storage of ten thousand records; stored data points can be selected for printing; supports dual retrieval of information by time and user name, meeting the needs of large data volume storage.
• Built-in micro printer and USB universal data interface, convenient for data output and transmission.
• Lightweight design, convenient for changing the detection location.

Test Principle

This product adopts the negative-pressure test principle. By evacuating the vacuum chamber, a pressure difference is created inside and outside the specimen immersed in water, and the escape of gas from the specimen is observed to determine the sealing performance of the specimen; by evacuating the vacuum chamber, a pressure difference is created inside and outside the specimen, and the expansion of the specimen and the shape recovery of the specimen after releasing the vacuum are observed to determine the sealing performance of the specimen.
