Composite Wall Apparatus

The apparatus consists of a pair of M.S. plates, Bakelite, brass/aluminum. These plates in series on either side of the heater form a composite wall.  The whole unit is clamped in a frame, which can be viewed through the Perspex sheet. The thermocouple tapings enables us to find out the conductivity and resistance of the composite walls.
