Digital Rockwell Hardness Tester

A hardness tester is a key Measuring Testing Instrument in material quality control, serving as a critical means to judge the performance of metal materials and finished product parts. By definition, hardness refers to a material’s ability to resist permanent deformation caused by the pressure of another hard object under specific test conditions—whether in industrial production or laboratory research, this property directly reflects a material’s wear resistance, strength, and durability, making higher hardness equivalent to better resistance in most application scenarios. As a trusted provider of testing solutions, Mikrosize has developed this Digital Dual Rockwell Hardness Tester, a high-performance Measuring Testing Instrument that combines a novel, ergonomic appearance with stable operational performance. It adopts intuitive digital display technology to eliminate reading errors from traditional analog dials, paired with microcomputer control systems that automate key test steps (such as indentation application and holding), seamlessly integrating mechanical precision and electronic intelligence to ensure consistent, accurate Rockwell hardness testing results.

This tester stands out with a comprehensive set of practical features tailored to diverse industrial needs. At its core is a high-precision stepper control system, which drives the indenter with micron-level accuracy to avoid manual operation deviations; the touch screen interface further simplifies use, allowing operators to set parameters (like test force and holding time) with just a few taps, even for those with limited professional training. For multi-standard testing scenarios, it includes a built-in HR, HB, HV hardness conversion ruler, enabling direct conversion between common hardness scales without the need for external calculation tools. To facilitate data management, it is equipped with a compact built-in printer that can instantly output test reports—including single test values, average values, and statistical deviations—while the RS-232 data output interface supports seamless connection to computers or factory MES systems, realizing real-time data storage and traceability. Beyond functionality, the tester’s structural design prioritizes durability: its main frame is made of high-strength cast iron, ensuring excellent rigidity to resist vibration interference during testing, and the extra-large testing space (with adjustable table height) can easily accommodate larger workpieces such as heavy castings or thick metal plates, eliminating limitations on sample size. Moreover, its complete standard configuration—including a full set of indenters, test blocks, and calibration tools—meets the testing requirements of all Rockwell hardness scales (from HRB for soft metals to HRC for hardened steels), covering most metal processing scenarios right out of the box.

In terms of application scope, this Digital Dual Rockwell Hardness Tester is widely suited for hardness testing across multiple industries and material types. It is particularly essential in the automotive and machinery manufacturing sectors, where it tests key components like quenched crankshafts, tempered gear teeth, and annealed connecting rods to ensure they meet design strength standards. In the casting industry, it effectively evaluates the hardness of cold hard castings (used in heavy-duty machinery) and malleable castings (common in pipe fittings), helping manufacturers identify defects like uneven heat treatment. For alloy materials, it handles everything from hard alloy steels (used in cutting tools) to non-ferrous metals such as aluminum alloys (aerospace components) and copper alloys (electrical connectors), providing reliable data for material selection and process optimization. Additionally, it is widely used in quality inspection laboratories for bearing steels—critical for ensuring the long service life of bearings in industrial equipment. Backed by Mikrosize’s professional after-sales support (including on-site installation, calibration, and maintenance services), this tester not only delivers accurate testing performance but also provides long-term operational stability, making it a valuable asset for businesses seeking to enhance quality control efficiency.
