NDL-V201 Non-destructive Leak Tester

Product Introduction:

Specifically designed for the integrity testing of package seals, this instrument utilizes the vacuum decay + pressure decay method. It is a completely non-destructive testing technology suitable for non-destructive micro-leakage testing of various empty/pre-filled syringes, ampoules and powder vials (glass/plastic), filled capped bottles, other rigid packaging containers, and electrical components.

Technical Features：    

Ø Industrial-grade touch screen computer with Windows operating system for real-time viewing of test data and curves;

Ø Uses the principle of dual sensors for vacuum and micro-pressure difference for non-destructive testing of package seals;

Ø Precise pressure testing system improves testing accuracy significantly;

Ø Uses world-renowned pneumatic components,micro-pressure difference and pressure sensors for stable and reliable performance;

Ø Adjustable vacuum, testing, and infiltration times are stored in a database to ensure consistency of testing conditions;

Ø Real-time display of test curves with intelligent data statistics for easy and quick viewing of test results;

Ø Complies with China GMP requirements for data traceability, meeting the needs of the pharmaceutical industry with multi-level permission management settings;

Ø Automatic data storage and automatic memory in case of power loss;

Ø Historical data can be quickly reviewed, and it is equipped with a mini printer and standard data interface for convenient data printing and transmission.

Testing Principle:

The main unit is connected to the test chamber, and the sample is placed inside to draw a vacuum. There is a pressure difference between the inside and outside of the sample, and the gas enters the vacuum decay chamber and the main unit through the leak hole. The main unit uses a pressure sensor and a differential pressure sensor to monitor the change in vacuum inside the test chamber, and judges whether the sample is qualified based on the change in vacuum.
