ABSTRACT:
A method and apparatus for quickly determining leakage of a test chamber in a production environment wherein a reference chamber is exposed to the same temperature effects as those existing in the test chamber and gas pressures are applied to the reference and test chambers and the pressures are compared in the test and reference chambers and relative changes of such pressures are read as a function of leakage.
