Nixma’s leak detectors use helium as a tracing gas, and do you know why?
Why helium?
We use helium leak test to measure the amount of gas (leakages). Helium is used to locate and measure the size of leaks into or out of a system or containing device. Helium is the best choice to find leaks because of its non-toxic, inert, non-condensable and non-flammable properties. Due to its small atomic size as well, helium passes easily through leaks.
Helium is also inexpensive and is available in various size cylinders, thus helium leak detection offers the best accuracy.
