MTR-X Benchtop Hardness Tester

Ernst MTR X Hardness Tester: Innovative Solution for Testing the Hardness of Metals

The Ernst MTR X hardness tester represents a significant breakthrough in metal hardness testing, thanks to its innovative Esatest® principle. This advanced hardness determination method allows operators to take measurements even in the most difficult to reach places, such as interiors, cavities, couplings and gears.

Esatest® Principle: An Innovative Approach The Esatest® principle, developed by Ernst, is a revolutionary approach to hardness measurement that uses the correlation between penetration depth and variations in residual electrical resistance. This technology uses a special indenter, enriched with boron to make it conductive, that provides measurements based on variations in electrical resistance induced by varying loads. This indirect method offers several advantages, including the ability to measure at very low loads to minimize damage to finished parts and the ability to perform tests in locations inaccessible to conventional instruments.

Key Features of Esatest® Technology:

• Measuring Capability: The system is capable of measuring over a wide range of loads, including very low ones, and displaying the results in various hardness scales (Brinell, Vickers, Rockwell and Super Rockwell).
• Technology: Thanks to the conductive properties of a boron-enriched diamond penetrator, Esatest® technology exploits the correlation between penetration and residual electrical resistance. The chemical plasma deposition method is used to create the boron-enriched diamond penetrator, which improves electrical resistance measurements.

With the ACCREDIA calibration certificate according to the DIN 50158-2 standard, the MTR X durometer is a highly reliable and accurate solution for checking the hardness of metals.
