TT SERIES Materials Testing Testorr™

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 the five interchangeable hot zones, each with its own thermal and atmosphere capabilities, are available for use with the standard vacuum chamber. Collectively, the heating systems provide for uniform specimen temperature 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.
