The TS-VDL1 Vacuum Decay Leak Detection Tester is engineered on the principle of vacuum decay to identify micro-leaks in finished packaging. Suitable for both micro-leak detection and integrity testing across a wide range of packaging formats, the instrument is well suited to pharmaceutical, food, and chemical packaging applications, including vials, ampoules, HDPE bottles, and prefilled needles.
As a non-destructive testing solution, the TS-VDL1 requires no sample preparation, allowing tested packages to remain intact and fully usable after inspection.
Key Features
Dual-Sensor, Dual-Cycle Technology for Non-Destructive Testing
The TS-VDL1 combines dual-sensor and dual-circulation system technology, incorporating high-quality absolute pressure and differential pressure sensors with an accuracy of 0.1% FS. This configuration enables reliable detection of both large and small leaks, accurate calculation of leak hole diameter, and a clear pass/fail determination.
A non-destructive testing method is used to leak-test the finished package, and the sample remains undamaged after testing.
High Sensitivity and Reliable Repeatability
For rigid samples, the instrument achieves a detection sensitivity as fine as 2 μm, with excellent test repeatability. Stable instrument performance and low operating noise further support consistent, dependable results.
Premium Imported Components for Superior Performance
The tester is equipped with a branded vacuum pump offering a pumping speed of up to 4 m³/h and a noise level as low as 60 dB. Its high ultimate vacuum is complemented by a convenient oil-level indicator that simplifies monitoring and replacement.
