| 描述： |
电动式测试，试验力的施加、保荷和卸荷自动完成。消除人为操作误差，使用方便。其特点：试验力小，留下微小压痕。
适用范围
表面淬火钢，铜、铝合金等薄板，硬质合金钢，镀锌，镀铬，镀锡，材料表面热处理和化学热处理等。
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.
