low cost o3 leak check pdf

If there is a leak, it will cause the gas to move from a high pressure to a low pressure and generates a turbulent flow that is sensed by the gas leak detection equipment. This type of routine testing is widely used for industrial applications to ensure a sound structure in critical components and assemblies in the prototype stage and after ...
