Utilises a Sodium Heatpipe

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 1100°C.

The furnace heater is of the non-inductive bird-cage
design insulated by twin bore alumina tubes. The heatpipe
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.
