Abstract
The present invention relates to a leak checking method for systems filled with fluids. A test gas, preferably helium, is introduced into the fluid and test gas escaping through any leak in the wall of the system is detected with the aid of a test gas sensitive detector. This method allows highly sensitive and continuous leak checks.
