The iRock-150 Touch Screen Digital Rockwell Hardness Tester from Mikrosize is a modern instrument designed for accurate and efficient hardness measurement. Combining an 8-inch large touch screen with a weight loading system that applies the lever principle, it delivers highly accurate test forces for reliable results in quality control and material evaluation.
Key Features and Design
The iRock-150 offers three selectable total test forces: 60kgf, 100kgf, and 150kgf. Its automatic loading, dwell holding, and unloading of test force streamline the testing process. The screw lifting column ensures stable and smooth vertical travel, while the standard diamond Rockwell indenter and Φ1.5875 mm steel ball indenter can be quickly replaced manually. The instrument supports conventional Rockwell scales HRA, HRB, and HRC; additional scales require matching optional indenters.
A built-in hardness scale conversion function allows easy switching between different scales. The tester displays a real-time hardness variation curve and performs automatic data statistics and average value calculation. With a hardness resolution of 0.1 HR and an adjustable dwell time range of 0~60 s, it meets diverse testing requirements. An integrated internal printer provides instant test data output, and USB and RS232 interfaces enable data export. English is pre-installed, with multilingual customization available upon request. The maximum specimen height is 210 mm (extended height support available), and the throat depth is 165 mm. The instrument complies with ISO 6508, ASTM E-18, JIS Z2245, and GB/T 230 standards.
Applications
The iRock-150 is ideal for hardness testing of raw materials such as steel, cast iron, non-ferrous metals, and alloys, quickly determining whether materials meet production and procurement standards. It supports quality control of heat-treated workpieces, including quenched, tempered, annealed, and normalized parts, ensuring strength and wear resistance meet specifications. The tester is also suited for finished product delivery and sampling inspection, conducting batch testing on shafts, molds, gears, plates, and hardware parts to ensure qualified and stable performance.
Operation Interface and Software
The 8-inch touch screen provides simple and intuitive operation. The main interface displays time and date, test force loading, calibration, dwell time, hardness value, testing scale, indenter type, standby, conversion standard, conversion scale, and function menu. Users can select from 21 Rockwell measurement scales, including HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS, HRV, HR15N, HR30N, HR45N, HR15T, HR30T, and HR45T.
The software includes multiple hardness conversion scales with four reference conversion standards built-in: GB/T 172, GB/T 33362, ASTM E140, and ISO 18265. Conversion options vary by selected reference standard. The data processing function supports analysis of 2000 individual measurement data-sets and trend line statistical analysis for 1000 grouped data-sets with data review. An integrated internal printer is standard, with PC communication interfaces optional. The instrument calibration range is -3.0 HR to +3.0 HR with 0.1 HR adjustment step.
Standard and Optional Accessories
Standard delivery includes the main unit, diamond Rockwell indenter, Φ1.5875 mm steel ball indenter, test anvil, force adjustment handwheel, handwheel, emergency stop button, power cable, operation manual, certificate of conformity, and warranty card. Optional accessories include a Φ3.175 mm steel ball indenter, standard Rockwell hardness test block, and standard superficial Rockwell hardness test block.
Conclusion
The iRock-150 Touch Screen Digital Rockwell Hardness Tester from Mikrosize combines advanced features, intuitive operation, and robust data management for reliable hardness testing in manufacturing, research, and quality assurance.
