摘要
An apparatus for measuring the degree of vacuum of a multistage vacuum heat-insulating member and to a measurement method using the same includes a chamber in which a plurality of vacuum heat-insulating members are accommodated and which forms a sealed space; a shelf arranged within the chamber so as to support the plurality of vacuum heat-insulating members in a plurality of layers; a displacement sensor for sensing the displacement of each outer shell of the vacuum heat-insulating members stacked on the shelf; and a vacuum unit connected to the chamber so as to regulate the pressure of the internal space of the chamber.
