ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for leak testing a fluid containing chamber wherein the chamber is pressurized with a gas and is submerged in liquid. The bubbles of gas rising from the submerged chamber are directed past a predetermined location which is adjacent to a photoelectric detector. The electrical signals from the photoelectric detectors are counted and when the number bubbles exceeds a predetermined number a fault signal is activated indicating a leaking container. By grouping a number of adjacent photocells into a predetermined set, the apparatus can discriminate between random bubbles rising from the chamber as it is submerged, and a number of bubbles all originating from a given location.
