Automotive Climate Control, Engine cooling, Electronic and lighting, Chassis Assemblies Leak Detection Applications

Leak testing of automotive systems and components has become more demanding. ATC’s micro-flow and Mass Extraction leak test equipment have met these requirements in hundreds of applications.

ATC works with our customers from help you to define the maximum allowed defect size (diameter and length) using our proven correlation test methods and certified micro-geometries, to  provide you with the complete leak and flow test equipment.

Micro-Flow Technology

Micro-Flow Technology introduces a new dimension in leak testing. Unlike pressure decay, it offers a breakthrough in leak testing with short cycle time, temperature stability, and low measurement ranges that could only be achieved with helium mass spectrometry in the past.
