The iRocky-150/45CL Touch Screen Twin Rockwell Hardness Tester from Mikrosize is a high-performance instrument for accurate hardness measurement. Its electronic weighted mainframe eliminates traditional weights, enabling power-on-and-go operation. With six selectable test forces, it covers Rockwell, surface Rockwell scales, and plastic Rockwell scales, making it versatile for laboratories and industrial quality control.
Key Features and Operation
The tester adopts an 8-inch color touch screen with fast response and sensitive operation. It supports hardness scale conversion across multiple values. The maximum test height 230mm and throat distance 170mm accommodate various specimens. Hardness results can be printed directly. The interface includes five sections: Setting, Testing, Display, Diagram, and Program Setting.
Users can select standards such as ASTM E140, DIN18265, GB/T. Supported hardness scales include HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS, HRV, and superficial scales HR15N through HR45Y. Conversion scales vary by standard.
Testing Process and Results
After setup, turn the handwheel clockwise to raise the screw, bringing the standard block into slow, impact-free contact with the indenter until the display shows OK and the buzzer sounds. The initial test force is applied. The automatic main test force is then applied, held for 5 seconds (adjustable via delay control 2 to 60 seconds), and automatically removed while retaining the initial force. The hardness value appears. Each specimen requires at least 5 test points (excluding the first). The display shows the test force curve and countdown.
For curved specimens, curvature radius correction improves accuracy. Users can set standard values and upper/lower deviations for quick pass/fail screening. The PASS display shows measurement scale, conversion scale, and deviations. Data statistics include maximum, minimum, average, and deviation range, with delete and print options. Language and test conditions are customizable.
