Trace-A‑Gas is a premium leak detection solution. Trace-A‑Gas is a 5% Hydrogen and 95% Nitrogen mixture which is non-flammable, non-toxic and safe for the environment. When used with a suitable electronic leak detector, Trace-A‑Gas will enable engineers to detect much smaller leaks than they can with Oxygen Free Nitrogen and a leak detection spray.

  • Hydrogen is the smallest molecule, enabling it to move rapidly through the system and quickly locate leaks
  • Trace-A‑Gas can detect much smaller leaks than other methods: it is up to 100 times more sensitive than leak detection spray and can detect leaks of less than 5 grams a year
  • Trace-A‑Gas tests all areas of the system, including insulated or difficult-to-access pipework where leak detection spray cannot easily be used
  • Using Trace-A‑Gas provides real-time results: spend less time on site
  • Using Trace-A‑Gas can reduce costs by avoiding the need to re-work
  • Suitable detection can quickly identify the Trace-A-Gas product, enabling engineers to easily locate a leak
  • Non-flammable, non-toxic and safe for the environment
