Tracer Gas is a safe, non-flammable, and non-toxic mixture consisting of 5% hydrogen and 95% nitrogen. It is commonly used in leak detection due to its ability to safely identify even the smallest leaks in various systems. When paired with a water leak detector such as SNIFFER430, the gas helps pinpoint leak locations efficiently. Since hydrogen molecules are small and highly mobile, they can easily escape through leaks, making detection quicker and more accurate. This environmentally friendly method is widely used in industries that prioritize both safety and precision.
We are commonly asked about where to find Tracer Gas. So below, we've put together a list of suppliers to help you get started. In addition to this, you will probably want to do your own search for local suppliers. We've also included below a list of search terms that could help you find the best option for you. In general, Tracer Gas can be found from stores that deal with industrial gases, welding supplies, and sometimes professional tool supplies.
We recommend looking for a refillable aluminum tank so it is light and portable. Around the size of Q1 in the size comparison image above, or perhaps a bit larger. A tank around this size should work for around 5-7 leak detections in regular houses. But this depends on many factors of course. Please see our guide for more precise calculation of Tracer Gas Volume and Usage.
