Qualitek mR: Muti-Range Leak & Flow Tester
The proven standard for fast, reliable leak testing in light- to-medium duty industrial applications.
Qualitek mR combines the latest advances in multi-range (mR) leak and flow testing technology with the expertise and reliability of Uson.
Versatile & Affordable
For many years, Qualitek has been the proven standard for fast, reliable leak testing in industrial markets. this versatile and affordable product offers high-quality and accurate results for light- to medium-duty industrial leak testing applications.
Today’s mR line combines the best features of predecessors into one efficient and easy-to-use tester. Backed by Uson’s world-renowned reputation, Qualitek mR sets a new benchmark of accuracy and dependability in leak testing equipment for multi-range leak and flow testing equipment. Designed to be used on the benchtop or mounted into automated systems, the Qualitek mR is impressively simple to use. The convenient and easy-to-read display lends efficiency and helps prevent errors.
Qualitek mR is a highly configurable system that accepts a full range of tests and transducers. It contains the most current leak testing technology, including a powerful toolbox complete with a full menu of options including:
• Pressure profile
• Charting
• Data analysis
• Programs storage
• Scroll-and-click control wheel
