Tracer Gas

National Tracer Gas is a blend of 5% Hydrogen and 95% Nitrogen rendering it completely non-flammable.

The smallest molecule is the diatomic hydrogen (H2) with a bond length of just 0.74A. This makes it the best option for finding the smallest leaks in critical systems*.

*When used in conjunction with leak detecting equipment.
