MTRX Macro & Micro-Hardness Tester for Testing a Gear Tooth, OD or ID.

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 a indenter specially coated with a resistive material to measure changes in resistivity as the indenter is progressively penetrates 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 esatest can fit into test tight areas like small id test samples The esatest can fit into test tight areas like gear teeth
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 conductivity depth measurement method illustrated
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.
