The Pioneer of Modern Leak Testing

Uson Air Leak Tester & Air Flow Test Equipment

Uson automatic air leak testers and air flow testing equipment are available in a variety of different formats. Our wide range enables us to cover most applications with a tester specifically configured for the intended test.

Uson Testers Perform Many Air Leak Test Methods & Operating Modes

Air Leak test operating modes and test methods include, pressure decay, mass flow, differential flow, pressure change, volume verification, occlusion testing, seal creep testing, and much more.

Why Use Air Leak Testers?

Using Air leak testers provides clean, fast, non destructive and repeatable testing. Test results are non-subjective, requiring no operator interpretation and the data is easily exported to spreadsheet or other format for analysis and R&D studies. Leak testing using air as the test medium is the most popular automated method in use and the testers themselves are easy to use.

For more challenging applications, Uson produces custom pneumatic circuits.
