The Oberon R uses a Sodium heat Pipe to ensure an exceptionally low temperature gradient along the furnace core. It is ideal for the realization of Aluminium, Silver or Copper ITS-90 Fixed Points.
It may be used as a blackbody source over the range 450°C to 1090°C.
The furnace heater is of the non-inductive bird-cage design insulated by twin bore alumina tubes. The heat pipe is designed so that the inner wall is not subject to thermal expansion stresses from the outer wall before the heat pipe reaches conduction temperature. The working fluid is permanently and safely sealed within the plasma-arc welded enclosure.
