Study of thermal conductivity

This experimental setup allows the study of heat propagation in different metal bars in a steady state.
The airtight metal enclosure ensures the vertical positioning of the bars through a simple clamping system. The submersible pump (provided) generates water circulation from a thermostatic bath (not provided) to the enclosure. This keeps the end of the rods at a fixed temperature.
The other end of the bars can be left in the open air or maintained at a constant temperature using a second enclosure (ref. 253 146 to be ordered separately).
Steady state is reached in about twenty minutes.

The metal bars are partially covered with a low-reflectivity black strip allowing simplified measurements with a thermal camera. This method has the advantage of providing access to the temperature of all points along each rod at any given time, unlike what can be achieved with conventional temperature sensors such as thermocouples.

For further exploration, experiments can be conducted in transient state (kinetic monitoring) using the enclosure plugs (ref. 253 148 to be ordered separately).
