The Krypton-85 Leak Testing method is a highly sensitive technique used to measure fine and gross leak rates in high-reliability devices. It is the preferred method to characterize small leak rates in critical military components.
The advantages of Krypton-85 over other methods include extremely fast test times, lower overall testing cost, lower leak rate detection.
The Krypton-85 method is also capable of finding thermally induced or pressure induced hermetic failures and has proven to be highly effective in the failure analysis process.
