The Pioneer of Modern Leak Testing

Vector Leak Tester: The ultimate in leak testing performance, speed, flexibility and durability

(Chinese Translation)

One of the fastest and most powerful leak testers on the market, the Vector leak tester line raises performance to new levels of efficiency and productivity. Their unrivalled speeds enable you to conduct leak and flow tests faster, increasing production like never before.


Because leak testing accuracy and repeatability is critical

Count on Vector leak testers to deliver the utmost in accuracy and repeatability while eliminating false rejects and keeping defective products from reaching the market. Vector software runs in a Windows® 10 environment making it extremely powerful yet very simple to use.

Available in multiple formats

Vector leak testers are available in bench top, 3U and 6U formats, all featuring Uson engineered pneumatic circuits optimized for specific leak and flow testing applications. The Vector’s modular design lets you expand your system’s capabilities as needed.  A single Vector leak tester can perform up to 10 independent or concurrent tests.  In addition to supporting unlimited types of leak and flow tests, the unique flexibility of Vector software allows you to add or modify functionality as future requirements dictate.


Harnessing the power and security of Windows 10

The embedded Windows 10 operating system makes  the Vector leak tester extremely powerful, yet simple to use while providing security updates to protect your system network. Its unique modular design lets you choose only the features you desire while still allowing  you to easily and economically expand capabilities as needed.
