Optima vT High Versatility Leak Tester

Leak testing versatility at your fingertips.

Optima vT offers Uson’s industry-leading reliability and advanced leak testing technology in a highly configurable and versatile tester. A comprehensive user interface puts control and information directly in your hands via the large, clear touch screen display. Optima is also available with both local (A3) and network (A3N) advanced authorization and authentication software upgrades to enable FDA 21 CFR Part 11 compliance guidelines.

The Optima vT is designed with utmost versatility in mind. Mounting options include standard and custom cabinets, flat panels, articulated pendants and more. Testing techniques include pressure decay, differential pressure decay, mass flow measurement, burst and occlusion testing and many others. At the heart of the Optima vT is Uson’s powerful TCU2, the second-generation Test Control Unit offering unparalleled flexibility in each test channel. The 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. Incredibly, a single channel Optima vT tester can test up to four independent cavities simultaneously while the two-channel tester can handle up to eight, allowing for significant cost advantages.

USON’S TCU2 provides unlimited leak and flow test design.

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.

Just like other Uson products, the Optima vT comes equipped with a comprehensive software toolbox that simplifies test setup and communication. It even includes pre-loaded common test types, allowing you to quickly add the necessary information about your part and fine-tune and optimize the test to perfection.

Leak testing innovation 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.

Don't compromise on reliability and performance. Choose Optima vT for unparalleled leak testing technology, versatile configuration options, and a user-friendly interface that puts control and information directly in your hands.

Advanced security features for 21 CFR part 11 compliance.

The Optima vT is now available with  A3N (Advanced Network Authorization and Authentication)   A3 (Advanced Authorization and Authentication) .  The A3 upgrade option offers advanced security features including user authentication through individual passwords or roles and the ability to log and monitor changes to parameters which enables compliance with standards such as 21 CFR Part 11 (U.S), MHRA/EU Annex 11 and others.
