Abstract: A testing apparatus is provided for comparative testing of disk passage resistance of various disks in a high energy loss disk stack to detect blocked, broken down or irregularities in the various disks or individual passages thereof. The testing apparatus includes a plug which is sealably movable within a central core of the disk stack to supply air to labyrinth passageways formed at predetermined stack heights by aligning an air outlet on the plug with the labyrinth passageways formed at that stack height. The plug is connected to a pressure gauge calibrated to indicate a normal range of labyrinth resistance. Readings below the normal range indicate broken down or low resistance labyrinths while readings above the normal range indicate high resistance or blocked labyrinths.
