Specific Heat Capacity Module: The Specific Heat Capacity Module is suitable for measurements on all solid/semi-solid materials with not too low a thermal conductivity. The measurements are made with a specially designed sample holder: a sensor with an Au-cell attached. To measure, put the sample inside the Au-cell and insulate the setup with Styrofoam. The only requirement regarding the sample is that it should have a reasonably flat contact surface.
