A unique tester mod. UMT has been developed to allow for measurements of ALL COMMON hardness scales: instrumented indentation with continuous force-displacement monitoring and automatic Oliver-Pharr calculations of stiffness, hardness and Young modulus within an unmatched wide range from 100 nN to 1 kN, with Berkovich, conical and cube-corner indenters, Rockwell with both Brale and ball indenters, Knoop, Vickers, Brinell, sclerometry (both micro-scratching with lengths from microns to centimeters and nano-scratching with reproducible depths from 1 nm to 100 nm). Comparison of results per any hardness scales on the same specimens without their removal allows for in-depth investigations of surface properties. Multi-sub-loading-unloading cycles during instrumented indentation allow for studies of hardness versus depth of penetration.
