Hardness testing equipment for heat treatment shops should be selected according to real production needs. A Rockwell hardness tester is useful for fast HRC checks after quenching and tempering. A Micro Vickers hardness tester is important for case depth, carburized layers, nitrided layers, and induction-hardened zones. For shops that need customer-ready reports, the setup should also include calibration blocks, correct indenters, fixtures, sample preparation equipment, microscope inspection, and software export functions. This makes the testing process more stable, traceable, and professional. If you are planning to build or upgrade a heat treatment QC lab, share your parts, materials, processes, hardness standards, and reporting requirements before ordering. A complete recommendation can help you avoid missing key equipment and improve long-term inspection reliability.
