Achievement of experiences in adiabatic conditions (isolation according to the outside)

Study module of the linear conduction:

- Metallic cylinder Ø 25 mm heat emitter, isolated from the outside, equipped with three temperature probes distributed linearly.

- Metallic heat receiver cylinder, isolated from the outside, equipped with three temperature probes. This element is cooled by circulating cold water

- Brass demonstration cylinders Ø25, in stainless steel Ø25 and in brass Ø15, different metals are isolated from the outside. They are equipped with three temperature probes spaced linearly. The sample change occurs rapidly by simple action on a spring clamp lever. This module allows to study the influence of the nature of materials and the contact surface between the elements on the transmission of heat energy.
