| HRM-45DT型电动表面洛氏硬度计是一种通过电动加载、保荷卸荷的半自动测试金属材料表面硬度的洛氏硬度计。具有操作更简便、压痕微小、精度高等特点。 适用范围
表面淬火钢，铜、铝合金薄板，带钢,硬质合金钢，镀锌，镀铬，镀锡，材料表面热处理和化学表面处理的各种金属材料。 HRM-45DT Motorized Superficial Rockwell Hardness Tester adopts motorized testing method. Its testing force can be loaded, kept and unloaded automatically. Avoid man-made error and easy to use. The characteristics of the instrument is light testing force and therefore, leaving very small indentation. Usage Range:
Surface hardened steel, copper, aluminum alloy thin sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface hardened treating and chemical treating materials, etc.
