INFICON - Operating Instructions EXTRIMA
The major advantages of Hydrogen Tracer Gas* are:
• It is the cheapest of all tracer gases (standard industrial grade
mixtures).
• The natural background concentration in air is only 0.5 ppm.
• Hydrogen is very easily vented away from the test area,
thereby minimizing background problems.
• Hydrogen is non-toxic, 100% environmentally friendly
and non-flammable.
• Hydrogen is a renewable natural resource.
• Hydrogen is a low viscosity gas which spreads very rapidly
inside the test object and easily penetrates a leak. After
testing it is easy to eliminate the gas from the
test area.
*Whenever the word Hydrogen Tracer Gas is used throughout this manual it implies
that the hydrogen gas is safely mixed with Nitrogen in the proportions 5% H
