Volumetric Leak Tester

Pressure Decay Leak Tester without an air supply!

The volumetric leak tester uses a plunger to generate a fixed volume of air without being attached to house air. No house air needed! This leak tester was originally conceived for filling and performing a pressure decay test on balloon catheters but has been expanded to multiple leak testing applications like chamber testing etc. Chamber testing is ideal for performing pressure decay tests on sealed parts such as sealed electronics or wearables.
