ABSTRACT:
A device includes a measuring assembly, a fluid pressure assembly, and a manometer. The measuring assembly includes a heating member defining a first contact surface, a cooling member defining a second contact surface facing the first contact surface, a platform, and a sleeve. The sleeve is configured far hermetically adjoining the heating and cooling members and allowing movement of the heating and cooling members relative to each other. The sleeve and the first and second contact surfaces form a cavity for receiving fluid material to be measured. The platform is configured for controlling the relative movement of the heating and cooling members to adjust the length of the cavity. The fluid pressure assembly is configured for compressing the fluid material into the cavity. The manometer is disposed on the sleeve or the fluid pressure assembly and is configured for detecting a fluid pressure of the fluid material in the cavity.
