Helium Leak Standards
Helium Leak Standards
High-precision, traceable leak standards for helium-based leak detection systems
Helium is the preferred tracer gas for detecting even the smallest leaks. Our helium leak standards are built for stability, accuracy, and seamless integration into vacuum or sniffer-based test setups.
Applications
Designed for high-sensitivity leak testing across a range of industries:
- Aerospace & Defense
- Automotive (fuel systems, EV batteries, components)
- Medical Devices & Life Sciences
- HVAC & Refrigeration
- R&D and Manufacturing Environments
Compatible Testing Methods: Spray, sniffing, hard vacuum, accumulation, and helium bombing techniques.
Leak Standard Configurations
Reservoir Style
- Self-contained helium supply
- Ideal for stable, low leak rates over extended periods
- Minimal setup — no external gas needed
- Available with gauges, isolation valves, or custom fittings
Open Style
- External helium supply required
- Best for higher flow rates or integration into test fixtures
- Flexible configurations for unique test environments

Frequently Asked Questions
Helium’s tiny atomic size, low background presence, and high detectability make it ideal for high-sensitivity applications. It’s inert, non-toxic, and works with widely available detection equipment.
Properly maintained helium leak standards can last indefinitely. Reservoir leaks may need periodic refilling. All standards should be recalibrated at regular intervals — most commonly annually.
