A method and apparatus for leak testing a hollow body wherein the hollow body is placed in a test chamber. A prechamber is brought to a desired pressure, then connected with the test chamber. The pressure in the test chamber is stored at a certain point in time on an input side of a differential pressure sensor and then the course of the test chamber pressure is compared with reference pressure thus formed. Any pressure compensation which occurs if leaks are present in the hollow body is recorded as an indication of such leakage.
