465 High Temperature Metrology Furnace. Temperature range 200°C to 1200°C.
The recent addition to our long-established range of metrology furnaces offers an alternative for those who prefer 3-Zone furnaces to Heat-Pipe technology.
The 3 Zones create a controlled volume of constant temperature within the furnace in which High-Temperature Fixed Points such as Aluminum, Silver and Copper can be frozen and melted.
Because High-Temperature thermometers can be easily contaminated by metallic vapors, great care has been taken to eliminate the use of metals throughout the calibration volume.
The cell holder is made of Alumina.

Temperature Metrology Furnace.

Model  Description 
465  465 High Temperature Metrology Furnace.

Wide Temperature Range 200°C to 1200°C.
Covers ITS-90 Fixed Points from Tin to Copper in one furnace.
Long plateaus.
Self-Tuning controller optimizes each Fixed Points performance.
3 zones controlled to compensate for end loss to give a perfect profile.

A ceramic equalizing block is available comprising a closed ended tube, Alumina tubes to house the
sensors being compared, and Alumina powder to act as an equalizing media.
The sensor for the main controller is a mineral insulated type N thermocouple which has been found
to be more stable than the type R thermocouple.
In addition two slave controllers compensate for any temperature gradient along the furnace by
eliminating any temperature difference that they sense.
Connections are provided for a water supply of 0.5 to 1 liter per minute to cool the top of the apparatus.
Water supply and waste connections may be ordinary garden hose. Use without cooling is not
recommended above 700°C.
This 3-Zone Furnace can be used for the realizations of the Tin, Zinc, Aluminum, Silver, Gold and
Copper points, or with an optional equalizing block used for annealing or comparison calibration. 200°C
