珠海電動表面洛氏硬度計HRM-45DT型是一種通過電動加載、保荷卸荷的半自動測試金屬材料表面硬度的洛氏硬度計。具有操作更簡便、壓痕微小、精度高等特點。 適用范圍 表面淬火鋼，銅、鋁合金薄板，帶鋼,硬質合金鋼，鍍鋅，鍍鉻，鍍錫，材料表面熱處理和化學表面處理的各種金屬材料。 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. 技術數據（Technical Specifications） 表面洛氏標尺 (Superficial Rockwell Scales) HR15N, HR30N, HR45N, HR15T, HR30T, HR45T 初試驗力（Initial Testing Force） 3Kg(29.42N) 試驗力（All Testing Force） 15Kg(147.1N),30Kg(294.2N),45Kg(441.3N) 硬度讀取 (Indication of Hardness Value) 表盤式（Dial ） 保菏時間(Duration Time) 2 ~ 60S 試件較大高度 Max.
