Temperature range 450°C to 1000°C
For Aluminum, Silver slim fixed point cells and comparison calibration.
Model 426 Furnace is for Aluminum, Silver slim fixed point cells as well as for comparison calibration. 

• Connections are provided for a water 
  supply of 0.5 to 1 litre per minute. 

• Water supply and waste connections are 
  provided. 

• Use without cooling is not recommended 
  above 700ºC.

• The Oberon can be used with Blackbody 
  Fixed Point Cells.

Heat pipes provide the ideal conditions for the creation and maintenance of slim ITS-90 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 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.
