About This Product
The thin sample sits between the steam chest and the brass slab, and steam passing through the chest keeps one side hot while the slab hangs from its three-point suspension. Thermometer readings in the chest and the slab, together with the cooling curve of the slab, give the thermal conductivity. It is meant for poor conductors such as glass, ebonite and cardboard.
