  • Leakage detector for a sealed housing
    Publication number: 20020001462
    Abstract: To test the integrity of waterproof cases for cameras and like apparatus to be used underwater, a casing with a detector is provided. The air inside the casing is pressurized and the detector indicates leakage based on the difference between the pressurized air and atmospheric pressure. A decrease in pressure of the initial level of pressurized air implies leakage.
