What We Do

The Pioneer of Modern Leak testing

We took innovative technology we first developed for NASA during the Space Race and applied it to a wide range of automated industrial assembly applications. Even after 50 years of leadership we still manufacture the most versatile and reliable lineup of leak and flow testers in the industry. And no one has more combined leak-testing experience than the professionals at Uson.

What We Offer

Technology. Methodology. Guidance.

In addition to designing the industry’s best leak testers, our experienced staff helps manufacturers determine the best leak testing equipment for their specific application requirements. We provide guidance on different types of leak tests and testing methodology, and our new environmentally controlled calibration lab is at their disposal. We do this FREE OF CHARGE, since our goal is to help ensure our clients put safe, high-performance products on the market efficiently and cost effectively.
