Device for local temperature measurement, associated cell and method for use

A device for local temperature measurement that is suitable for obtaining temperature measurements of the immediate vicinity of the device, the device comprising:

• a cell comprising a thermally conductive base, the base having a generally cylindrical shape, and a first material having a predetermined fixed state-change temperature and arranged in the base,
• a thermal energy transfer device thermally connected to the base and to the first material,
• a local temperature measurement probe received in the base and in thermal contact with the first material,
• the thermal energy transfer device being adapted to cause a change of state of the first material in order to carry out at least one metrological verification of the local temperature measurement probe,
• wherein the device further comprises thermal insulating means configured for maintaining a uniform temperature within the cell, and
• wherein the thermal insulating means comprises at least one block bearing against an end face of the base.
