HRM-45DT型電動(dòng)表面洛氏硬度計(jì)是一種通過(guò)電動(dòng)加載、保荷卸荷的半自動(dòng)測(cè)試金屬材料表面硬度的洛氏硬度計(jì)。具有操作更簡(jiǎn)便、壓痕微小、精度高等特點(diǎn)。
適用范圍
表面淬火鋼，銅、鋁合金薄板，帶鋼,硬質(zhì)合金鋼，鍍鋅，鍍鉻，鍍錫，材料表面熱處理和化學(xué)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.
