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

• Adopts world-renowned SMC imported pneumatic components, with stable and reliable performance.
• The system uses digital presetting of the test vacuum degree and vacuum holding time, ensuring the accuracy of test data.
• Automatic constant-pressure air replenishment further ensures that the test can be carried out under the preset vacuum conditions; vacuum pumping, pressure holding, pressure replenishment, timing and blowback are all fully automated with one-key operation.
• The system adopts microcomputer control, combined with an LCD display and physical key operation, convenient and efficient.
• 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.
