簡單介紹：
HRM-45型手動(dòng)表面洛氏硬度計(jì)
詳情介紹：
HRM-45型手動(dòng)表面洛氏硬度計(jì)是一種普及型的，專門用于測試金屬材料表面硬度的洛氏硬度計(jì)。本機(jī)采用機(jī)械式手動(dòng)加載操作，無電器裝置。具有操作簡便，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。
HR-45M Manual Superficial Rockwell Hardness Tester adopts mechanical and manual testing method, without electrical device. With simple appearance, it uses as popular type Rockwell Hardness testing instrument.
Usage Range:
Surface hardened steel, copper, aluminum alloy sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface heat treating and chemical treating materials, etc.
