Esatest MTRX Macro & Micro Hardness Tester
The Esatest MTRX is a specialized patented trans-portable digital micro hardness tester, using a unique measurement system for hardness testing in normally inaccessible locations and on odd specimen types. The tester uses an indenter specially coated with a resistive material to measure changes in resistivity, as the indenter is progressively penetrating the sample.
- Patented method for depth of indentation testing via electrical resistivity measurements on the indenter
- Tests inside diameters, gear teeth, irregular shapes, etc.
- Results not affected by deflection and vibration
- Test stand orients to position for testing on many angles.

|The inside diameter of a hardened test specimen |
presents a unique challenge for testing. Here the small
profile of the MTR indenter holder allows testing.
|The MTRX test stand allows the unit to rotate in three |
axes in order to reach difficult test positions like the
gear tooth hardness testing being shown here.
The test method employs a resistive coating on a diamond indenter that measures the progressive indentation of
the diamond and generates a test result in equivalent hardness values like Rockwell or Vickers.
