Optima vT Leak and Flow 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.
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.
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.
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.
