Helium Leak Testing – Ultra-Sensitive Leak Detection

Helium leak testing is the most accurate method for detecting even the smallest leaks in sealed systems. Using helium as a tracer gas, this technique ensures the integrity and safety of critical components.

Capabilities

• On-site helium leak testing for large systems and installations
• Overpressure and underpressure methods (vacuum and sniffing techniques)
• Leak spraying for pinpointing leak locations
• Outgassing analysis for vacuum integrity and contamination control
• Highly accurate detection sensitivity up to 5×10⁻¹² mbar·l/s

Example of reference Methods

• ASTM F2391-05 – Helium Mass Spectrometer Leak Detection
• ASTM F2338 – Non-destructive Package Leak Testing

Applications

• Hydrogen (H₂) trucks and high-pressure tanks
• Drivetrain and load-carrying components
• Roof boxes and structural parts
• Engine components under thermal and mechanical stress
• Design validation and test setup verification
• Durability and fatigue testing for safety-critical parts
