摘要： A measuring device having a first space for pressurizing an object to be pressurized and a second space independent of the first space. The measuring device is provided with a first exhaust valve that closes or opens a communication port for communication between the first space and another space. The open/closed state of the first exhaust valve changes depending on a pressure difference between the first space and the second space.
