Why Hydrogen?
• The lightest gas of all• Lowest viscosity of all gases (easy to fill,
evacuate and dissipate) • Low background (0.5 ppm)
• Environmentally friendly, sustainable
• Much cheaper than helium
• Non flammable (when diluted 5% in N2)
• Non toxic - non corrosive
Hydrogen Instrument advantages
• Simple and robust for industrial use• No vacuum pumping
• No need to draw sample into the detector
• Flexible design
• Easy to calibrate
• No maintenance
When simple methods are not good enough and mass-specs are too complicated...

When to use Hydrogen?
Hydrogen vs Pressure Decay
The Hydrogen Method... • can locate leaks• is independent of variations in
temperature• is perfect for testing soft objects• is independent of size of test
objects’ internal volume• has a higher sensitivity
(Pressure Decay from 10-2 ml/s Hydrogen Method from 5x10-7 ml/s)
Hydrogen vs Helium

Locating leaks in...• Buried and ducted cables
• Aerial cables
• Pipes and ducts
• In-house heating pipes
Outside Plant
Industry - instruments
• Manual Leak Location• Manual & Automatic
Leak Testing
Industry – Leak Test Systems
• Sniffer clamp test• Accumulation chamber
test (integral test)• Scanning
• Pump Method
