About Uson
Uson was founded in 1963 in Houston, Texas, with roots in high-accuracy leak testing technology first developed for NASA's space program. That aerospace heritage gave the company an early lead in precision measurement, and for more than six decades Uson has applied those methods to automated industrial assembly and quality-control applications around the world. As of 2023, Uson operates as part of PAC, a global manufacturer of advanced analytical instruments and a unit of Indicor.
Uson's core product line centers on automatic air leak and flow measurement instruments. The current lineup includes the Vector high-speed multi-channel tester, the Sprint iQ and Sprint mD compact and multi-channel testers, the Qualitek mR multi-range industrial tester, the Optima vT high-versatility tester, and the 628 differential pressure decay instrument. For package integrity, Uson offers the Qualipak series of vacuum decay and force decay testers. Testing methods supported across these platforms include pressure decay, differential pressure decay, vacuum decay, mass flow, occlusion, and burst testing, and units are available in bench-top, panel-mount, and fully integrated pneumatic fixture configurations.
Uson leak testers serve manufacturers in medical device production, automotive and electric vehicle battery assembly, pharmaceutical and food packaging, and general industrial manufacturing. In regulated sectors such as medical devices and pharmaceuticals, Uson equipment is routinely validated to FDA and ISO quality standards, making it a fixture on production lines for catheters, drug delivery components, surgical instruments, sealed packaging, automotive fluid systems, and EV battery enclosures.
Buyers seeking used Uson leak testers are drawn to the brand's reputation for robust construction, proprietary high-resolution sensors, and long service life. Because Uson has supported its instrument families across multiple generations, spare parts and calibration services remain available for older platforms, lowering the total cost of ownership on the secondary market. Facilities expanding capacity or replacing aging equipment often find that a pre-owned Uson tester delivers the same validated performance as new at a significantly reduced capital outlay.
