Features
- Five interchangeable, resistance-heated hot zones
- Temperatures of 300°C to 2500°C
- Pressure range of 10-6 torr to 2 psig
- Tensile testing hot zone has a 3.25" grip-to-grip distance
- Hot zones are designed for use in Argon, Helium, Hydrogen, Nitrogen,
Oxygen, or vacuum atmospheres
- Chamber is designed for use with optical and contact extensometry
- Temperature control accuracy of ±0.01% full scale
- Chamber is designed to accommodate various testing requirements
The Centorr/Vacuum Industries Testorr Furnace System provides a variety of
tightly controlled, elevated-temperature environments for materials testing
within the confines of a standard testing frame.
A choice of five interchangeable hot zones, each with its own thermal and
atmosphere capabilities, are available for use of the standard vacuum chamber.
Collectively, the heating systems provide for uniform specimen temperatures of
300°C to 2300°C in a wide range of atmospheres. In the high-temperature
region (1200° to 2300°C), a temperature uniformity of better than
±5°C is typical.
In addition to providing temperatures up to 2500°C, the Testorr Furnace
System has been designed to interface with optical and contact extensometers,
hydraulic grips, internal load cells and fixtures (3- and 4-point bend,
compression, etc.) used for high-temperature materials testing. Appropriately
sized ports are provided for water cooling, hydraulic and electrical connections
to each of the devices listed above.

** Operation from 10-2 torr to 10-6
torr requires selection of Model 06A6 diffusion pumping,
turbomolecular or cryogenic pumping systems.
*** Flammable gas safety systems are added to the Testorr
furnace if the option is exercised.
**** Consult vapor pressure chart.
