Precise Helium Leak Detection System SFJ-231

Features :

The Helium Leak Detector is an industrial vacuum detection and leak detection device designed to detect helium leaks in industrial and research environments.
It is capable of detecting helium leaks from 2, 3 and 4 (H2, He3, He4). It is non-toxic, inert, non-condensable, non-flammable and not normally present in the atmosphere at more than trace amounts (5 ppm).
Due to its small atomic size, helium passes easily through leaks.
The only molecule smaller than Helium is Hydrogen which is not inert.
It is also relatively inexpensive and is available in various size cylinders. So helium is the best choice of tracer gas to find leaks for a number of reasons.
