In the critical fields of aerospace, automotive manufacturing, metallurgy, and quality inspection, material hardness testing is non negotiable for ensuring safety, reliability, and product performance. As a leading supplier of precision measuring and testing instruments, Mikrosize takes pride in presenting its comprehensive lineup of digital Rockwell hardness testers—cutting-edge solutions engineered to redefine accuracy, efficiency, and user friendliness in material hardness testing.
Core Technology: Closed Loop Precision and Smart Control
Mikrosize’s hardness testers integrate advanced technologies that set them apart from traditional dead-weight systems. The Closed Loop control system with a high-precision load cell replaces conventional weights, significantly improving loading accuracy and ensuring more stable test forces. This innovation delivers superior repeatability and eliminates the mechanical wear associated with traditional systems.
The high-definition touch screen serves as the command center, offering an intuitive interface for direct selection of hardness scales, test forces, dwell times, and indenter types. Real time test force curves displayed on the coordinate axis provide complete visibility into the testing process. With a hardness resolution of 0.1 HR, these instruments deliver exceptional measurement precision.
The Mikrosize Hardness Tester Series
Mikrosize offers a versatile range of digital Rockwell hardness testers, each tailored to specific testing requirements:
iRocky-150DP uRocky-A MRocky-150T MRocky-45T
iRocky-150DP – A touch screen plastic Rockwell hardness tester designed for soft materials, featuring electronic-driven loading and comprehensive Rockwell full-scale capability.
uRocky-A – An automatic digital Rockwell hardness tester with motorized test anvil lifting, eliminating manual handwheel rotation for streamlined operation.
MRocky-150T – A touch screen Rockwell hardness tester with a weight-loading mechanism, built-in thermal printer, and 6-folder data management.
MRocky-45T – A superficial Rockwell hardness tester designed for surface-treated materials, thin sheets, and coated specimens.
Advanced Functionality Across the Series
Smart Data Management – The instruments automatically group and save experimental data: each group stores up to 10 data points with a total capacity exceeding 2,000 records. The system automatically calculates maximum, minimum, average, and standard deviation values.
Flexible Hardness Scales – Users can select from 15 Rockwell scales (HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS, HRV). Real time conversion supports HV, HK, HBW, and superficial Rockwell scales (HR15N, HR30N, HR45N, HR15T, HR30T, HR45T).
Intelligent Features – Upper/lower limit setting with audible alarm alerts users when results exceed tolerance. Cylindrical and spherical surface correction compensates for curved specimens. Software driven hardness value correction enables direct adjustment without complex manual intervention.
Multiple Data Output Options – Optional Bluetooth printer support, RS232, and USB interfaces allow on site report printing and data transfer to computers for further analysis. The uRocky series directly saves data in Excel format to a U flash drive.
Industrial Applications
Mikrosize hardness testers are widely applicable across diverse industries:
Heat-Treated Materials – Hard alloys, carburizing steel, quenched steel, surface-quenched steel, and bearings
Non-Ferrous Metals – Aluminum alloys, copper alloys, and soft metals
Surface-Treated Materials – Nitrided, induction-hardened, plated, and coated specimens
Soft Materials – Plastics, composites, friction materials, and non-metals
Thin Materials – Sheets of various thicknesses, galvanized, chrome-plated, and tin-plated materials
Compliance and Quality Assurance
All Mikrosize hardness testers strictly comply with internationally recognized standards, including ISO 6508, ASTM E18, GB/T 230.2, and JIS Z2245. This compliance ensures that test results are globally recognized and scientifically valid.
