PT-3070: Hydraulic Pressure Tester

The PT-3070 is ideally suited for testing small plastic pressure retaining components such as welded or bonded plastic components and tubing assemblies that are typically encountered in many disposable medical devices, i.e. balloon catheters. Tubing, small valves, fittings, balloons, etc. can be tested for burst, leak, fatigue, pressure or volume compliance and flow resistance. The unit can measure and plot pressure and volume compliance of elastomeric balloons, measure inflation and deflation times of balloon catheters, such as PTCA and PTA, and determine stent deployment characteristic, etc.
