The unit consists of two parts: a multi section bar for linear heat conduction studies, and a metal disc for radial heat conduction studies.

. Linear Heat Conduction Unit.

The unit has 3 sections which can be pressed tightly together. The first section is for heat input where a heater and three temperature sensors at 10 mm interval are installed. The center section has three temperature sensors at 10 mm interval. The last section is a heat sink section where cooling water and two temperature sensors at 20 mm interval are installed.
