TESTMASTER
- Vacuum Furnace For Mechanical & Physical Testing of Materials
|
|
Testmaster
vacuum furnaces are designed for physical and mechanical property
evaluation of high temperature ceramic and metallic materials. They can be used alone as a
bench top laboratory vacuum furnace or in conjunction with mechanical test machines, laser or
mechanical dilatometers, or load cells for thermogravimetric analysis. The Testmaster can
also serve as a multipurpose facility suitable for sintering, heat treating, brazing,
outgassing, and other high temperature thermal processing experiments.
Each vacuum furnace is supplied as a complete system including: vacuum
chamber; heat zone; power supply; vacuum pump; and a manual power control system.
Additional accessories and enhancements are optionally available to meet individual
requirements, including high vacuum pumps, automatic control systems, and data acquisition
equipment.

Testmaster vacuum vessels are made
completely from stainless steel, including the chamber, water jacket, and all flanges.
Each chamber includes top and bottom center ports for pull rods, load cells, dilatometers,
or other accessories. A valved sight window is provided for visual observations or
temperature measurements with optical and infrared pyrometers. Additional penetrations
include a high vacuum pump port, ports for vacuum gauges and pressure accessories, a port
for an ion/cold cathode gauge and three threaded ports for thermocouples or
instrumentation leads.
Metallic, graphite or Kanthal®
heat zones can be provided. The metallic heat zone uses a tungsten or molybdenum mesh
heating element and refractory metal radiation shields for a clean, contamination free
environment. The low thermal mass of the metallic zone allows rapid heating and cooling
for fast turnaround between experiments. The graphite zone is more durable and abuse
resistant, and requires less power to maintain temperature. The Kanthal zone is designed
for operation in air oxidizing atmospheres. Hot zones are designed for easy access and
long life at maximum rated temperatures.
