Hardness Tester

Rockwell hardness testers are instruments designed for fast and accurate measurement of the surface hardness of metals and various materials. They are widely used for evaluating the quality of steel, alloys, tooling materials, machined components, automotive parts, and heat-treated materials. By applying a fixed load and measuring the indentation depth, the Rockwell method provides simple operation, rapid testing, and excellent repeatability, making it one of the most commonly used hardness testing methods in quality control, material laboratories, and R&D applications. Taiwan Nakazawa offers a wide range of Rockwell hardness testers, including manual, semi-automatic, and fully automatic closed-loop control models to meet different production environments, material characteristics, and precision requirements. These testers can be integrated with hardness test blocks, diamond indenters, and data management software to help customers pass quality audits and ISO certifications efficiently while establishing a stable and reliable hardness testing workflow.

• Fast testing speed and excellent repeatability:

  The Rockwell hardness tester can complete measurements within seconds and delivers highly consistent results, making it ideal for high-volume quality inspection and rapid sampling to improve production efficiency.
• High precision and stable force control:

  Taiwan Nakazawa’s Rockwell hardness testers adopt high-accuracy load control technology that ensures stable hardness values ​​unaffected by operator differences, making them suitable for factories that must comply with ISO, IATF, and other international quality audits.
• Durable construction, low maintenance cost, and complete after-sales service:

  The testers feature a high-rigidity structure and long-lasting components suitable for continuous operation, supported by Nakazawa’s fast maintenance service, remote assistance, and training, ensuring reliable and traceable hardness testing with lower long-term operating costs.
