Air Leak and Flow Measurement

Uson makes available air leak testing equipment in a variety of formats and with various operating modes, including pressure decay, differential flow, mass flow, pressure change, volume verification, seal creep testing and more. Our range covers most industry applications, but for more demanding applications we are able to produce custom leak testing pneumatic circuits.


Here at Uson, we work closely with leading medical device manufacturers to create top quality devices, components and assemblies. We are pleased to house automated and semi-automated leak detection systems in order to design and manufacture excellent solutions. Examples of the range include: Optima VT (a multi-sensor leak and flow tester with advanced features), Qualitek (non-destructive package testers for bottles, canisters and pouches), Sprint (a multi-channel, bench top leak and flow tester) and Vector (a powerful, multi-channel leak and flow tester). Please follow the link to our website to view the complete range.


We also supply leak detection products and systems to the automotive industry. With more than 50 years in the business we have vast amounts of experience and knowledge which is widely regarded in the automotive industry. Our leak testers perform tests quickly while ensuring high accuracy and repeatability at the same time. They are widely used for testing engines, cylinder heads, blocks, transmissions, fuel and fuel injection systems, lamps, castings, pumps, motors, and more. Uson leak detectors enable high quality production by eliminating false rejects and defective products from the market.


Our leak testers are also used around the world to ensure that products meet the quality and safety standards at production stages. Used in various line speeds, Uson leak detectors save time and money by spotting machinery faults at initial stages. Uson leak testers feature qualities such as data collection, networking, statistical analysis and synchronous testing. They are widely used for testing various industrial products such as burners, compressors, water devices, water heaters, hydraulic blowers, manifolds, gas products, diving equipment, and more. Please contact us at Uson for further information and advice regarding our leak testing solutions.


The process of leak testing is essential in the packaging industry for achieving top quality results. As new packaging solutions emerge in the modern world, our leak testing equipment must prove versatile and effective.

Our leak testers are suitable for use with a range of packaging equipment and solutions for destructive testing for flexible packaging are also available.

Customers may choose from non-destructive, one-test devices through to multi-channel, multi-test systems suitable for use with a range of packaging types such as pouches, lidded trays, vials and induction sealed bottles.
