50 x 300mm Calibration Volume
Compact Heatpipe Furnace
Suits Aluminium, Silver or Copper Fixed Points
Can be used for comparison and infrared calibration
Model 426 is for aluminium, Silver or Copper slim fixed point cells.
The furnace core is a specially-designed stress-free isothermal heat pipe, which provides a very low thermal gradient along the core working length.
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.
The Oberon can be used with Blackbody Fixed Point Cells.
