Facts About Hydrogen/Forming Gas
Forming gas, a non-flammable mix of 5% hydrogen and 95% nitrogen, is widely used as a tracer gas for leak detection. The low hydrogen concentration ensures safety while providing excellent sensitivity for pinpointing leaks. Readily available in most countries as a standard shielding gas for welding, forming gas offers a cost-effective and efficient solution for various industrial leak testing applications. INFICON provides hydrogen leak detectors for all needs, including solutions for demanding environments and intrinsically safe instruments for hazardous areas.
