Module Information

MFT-5000 high temperature modules are an excellent option for running hardness testing at elevated temperatures.

sample at high temperature in hot hardness tester

Unique chamber design, exotic high temperature alloy materials, good thermal uniformity for repeatable data.

Environmental Control

The inert gas chamber allows reaching rough vacuum before purging the chamber with inert gas. This reduces oxygen concentration in the chamber and prevents oxidation of the sample surface and indenters.

Multiple Samples and Automatic Indents

Multiple indents across different samples or within same sample with only one click.


The table shows materials hardness vs temperature for certain metallic alloy. 

High temperature indentation data


The high temperature hardness module on the MFT-5000 is interchangeable to allow running several other standard and non standard high temperature tests on the same platform.

Isolate the high resolution load cells using innovative design and methods resulting in negligible thermal drift during the test.

Down force control

Real-time force control during the test. This allows to run several hardness standard on same tool.

Temperature Control

Close loop temperature control characterizes hardness at various temperatures.

XY Stage

The XY stage to create multiple indents automatically at various temperatures and locations.

Solution To

The Hot Hardness tester is used extensively across a wide range of industries:

  • Aerospace
  • Hard Coating
  • Lubricants
  • Metal
  • Polymer
