GAUGE FOR MEASURING DEPTH AND GAUGE CAPABLE OF MEASURING DEPTH AND INSIDE DIAMETER

摘要

A measurement gauge is provided. The measurement gauge includes an inner stopper which is in contact with the inner step of the hollow measurement object, an outer stopper which is supported at a predetermined position of the measurement object, a movable member which is linearly movably supported by the outer stopper, one end is connected to the inner stopper, And a depth indicator for indicating the distance of travel. With this configuration, it is possible to easily measure the depth of the expanded tube due to explosion employed in, for example, a heat exchanger flow of a nuclear reactor.
