The Pioneer of Modern Leak Testing

Qualitek 626 Pressure Decay Leak Tester


(Special Order Only) (Replacement = Raptor)

The Qualitek 626 is a cost effective differential pressure decay leak tester. The Qualitek 626 offers menu driven operation allowing for easy set up and results interpretation, reducing operator errors. The design of the Qualitek 626 makes it suitable as either a stand alone tester or as part of an integrated fully automatic test station.

The newer Raptor is now Uson’s mainstream leak tester for the entry level leak tester market. It can also be used in a wide variety of markets, industries, and applications where a bench-top design and small footprint is desirable. The Raptor as a replacement to the Qualitek 626 builds upon a great legacy and takes it to a whole new level and capability with Bluetooth connect and Apple iOS and Android smart device interfaces.
