Fully automated and integrate-able with a variety of PLCs and HMIs – a powerful solution for the systems’ integrator.


The MLC Leak/Occlusion Tester for Multi-Lumen Catheters.

Air or Nitrogen Leak Tester

The MF-11 performs fast, accurate leak tests with either air or nitrogen. It utilizes our ultrafast mass flow test method in which a constant pressure is maintained to the test part by a precision pressure regulator.

Thermal Mass Flowmeter

Our patented thermal mass flow meter and fill techniques are ultra-fast and produce repeatable results with very low pressure drop—ideally suited for high-throughput leak-test applications.
