The Pioneer of Modern Leak Testing

Optima vT: Superb versatility at your fingertips.

Optima vT offers Uson’s industry-leading reliability and advanced leak testing technology in a highly configurable and versatile package. A comprehensive user interface puts control and information directly in your hands via the large, clear touch screen display.

Uson’s powerful TCU2 lets you get creative

This second generation Test Control Unit offers unparalleled flexibility in a single test channel. TCU2 allows up to four high-resolution sensors and with its available custom pneumatic configurations, the sky is the limit on your leak and flow test design creativity.

For the most demanding applications

With a choice of one or two test channels, optional enclosures, a wide range of test types and custom pneumatics, the Optima vT takes versatility in leak testing to a new level. For demanding applications, choose high flow valves for fast filling larger volumes, or specify Uson’s proprietary differential pressure transducer for utmost sensitivity and repeatability. Even use two channels to test two cavities or parts simultaneously to reduce cycle time. With Optima vT, you’re in charge.
