|発明の名称||DEVICE AND METHOD FOR MEASURING POROUS MATERIAL CHARACTERISTICS|
PROBLEM TO BE SOLVED: To provide a device for measuring characteristics for a porous material provided with constitution capable of obtaining easily various characteristics of the porous material.
SOLUTION: The device 1 includes a storage part 3 for storing the porous material 2, a pressure detecting part 4 for detecting internal pressure of the storage part 3, a gas storage part 5 for storing prescribed gas introduced into the storage part 3, and a gas exhaust part 6 for exhausting the gas from the storage part 3. In this characteristic measuring instrument 1, an introduction volume of the gas into the storage part 3 and a discharge volume of the gas from the storage part 3 are controlled based on detection pressure detected by the pressure detecting part 4 to maintain the internal pressure in the storage part 3 at a constant level.
