PROBLEM TO BE SOLVED: To make possible simulation of at least a high-pressure underground environment. SOLUTION: This device has a globe box 3 with internal and external atmospheres isolated from each other, a gas circulating/refining device 2 for supplying the box 3 with a circulation gas having prescribed constituents and collecting the gas, and a high-pressure device 4 provided in the box 3 and having a high-pressure testing chamber 26 capable of being pressurized to an arbitrary pressure. The device 4 has a first cylindrical member 24 having the testing chamber 26 therewithin and having an upper surface opened so as to open the testing chamber 26 to the exterior, a first piston member 23 inserted from the opening of the cylindrical member 24 and capable of moving in close contact therewith, and a first cylinder device 16 for advancing or retreating the piston member 23.
