Helium is used to find small leaks or possibly larger leaks in bigger volumes. The helium is used as a tracer gas and its concentration is measured. Helium is one of the smallest gas molecules and is inert. Being inert it is relatively safe to use and will not react with any of the materials within the part to be tested. Helium leak testing can be generally between one thousand and one million times more sensitive than using pressure decay techniques. We can provide this service in Oman in collaboration with our associate.
