PROBLEM TO BE SOLVED: To provide a measurement device capable of measuring a load working on a test piece with high accuracy in a measurement device for measuring mechanical characteristics of a material in a high pressure gas.SOLUTION: A measurement device 1 for measuring mechanical characteristics of a test piece a comprises: a container 10 for storing the test piece a; and a measurement mechanism 15 inserted into the container 10 and measuring a load applied on the test piece a. The measurement mechanism 15 includes: a load rod 20 for applying a load to the test piece a and an outer cylindrical part 21 for storing the load rod 20 on the upper part thereof and storing the inner cavity member inside thereof; and a sensor member for measuring the load working between the load rod 20 and the test piece a. The load rod 20 can be placed in an airtight space 12 storing the test piece a by connecting the outer cylindrical part 21 in a sealed state to the airtight space 12 storing the test piece a in a sealed state. The load loaded on the test piece a can be highly accurately measured by the sensor member provided on the side wall of the inner cavity member.SELECTED DRAWING: Figure 1 |
