The device consists of a copper bar that is heated at one end and has a heat sink at the other. The test segment of the bar has thermocouples attached along its whole length and is adequately insulated. By collecting heat in a heat sink that is cooled by water, heat passed through the bar section can be monitored. A panel with controls and measurements is offered, allowing for simple operation and stable attachment of the instrument.

Experimental Objectives
