摘要： An apparatus for measuring airtightness of sealed bodies such as waterproof wristwatches. The apparatus comprises airtightly sealed container for an object to measure, means connected to the container for varying inner pressure thereof, and means for electrically detecting mechanical strain occurring at the surface of the object in the container when subjected to a varied pressure. The detection is performed, for precision purpose, by means of measurements of variations in reactance, electrostatic capacitance or the like responsive to changes in slight clearance between magnetic or conductive member engaged to a surface of the object and detecting coil or electrode opposed to the member due to the strain, or, for simpler determination purpose, by means of ON-OFF operation of relay contact means including stationary contact opposed to the object surface and movable contact engaged to the surface.
