Bench Hardness Tester MTR-X
Ernst's MTR X hardness tester represents a significant breakthrough in metal hardness testing, thanks to its innovative Esatest® principle. This advanced hardness measurement method allows operators to take readings even in the most difficult-to-reach areas, such as interiors, cavities, joints, and gears.
Key Features
- Measurement Capability: The system can measure across a wide range of loads, including very low ones, and display results in various hardness scales (Brinell, Vickers, Rockwell, and Super Rockwell)
- Technology: By leveraging the conductive properties of a boron-doped diamond indenter, Esatest® technology utilises the correlation between penetration and residual electrical resistance.
- Innovative testing principle (brev. Ernst) - Tests in inaccessible points compared to traditional hardness testers: gears, couplings, cavities, interiors, weld seams, HAZ (heat affected zone)
- 1 diamond indenter for the entire range of metals - Simplicity and speed of the testing process
- Continuous measurement of hardness at various loads - Immediate evaluation of the surface heat treatment - A single tool = Various detections
- ACCREDIA certification (ILAC MRA - mutual recognition Arrangements) - Offers a competitive advantage in markets where certification is required
Manufacturer
Ernst
Ernst have been driving the research and innovation in hardness testing for over 60 years. Ernst produce portable, automatic and bench-top hardness testers, covering all hardness testing requirements, together with products that extend their functionalities such as indentation readers and case depth analysers.
Esatest® Principle: An Innovative Approach
The Esatest® principle, developed by Ernst, is a revolutionary approach to hardness testing that leverages the correlation between penetration depth and changes in residual electrical resistance. This technology uses a special indenter, enriched with boron to make it conductive, that provides measurements based on electrical resistance changes induced by varying loads. This indirect method offers several advantages, such as enabling measurements with very low loads to minimise damage to finished parts and allowing tests in positions conventional instruments cannot reach.
