產(chǎn)品簡(jiǎn)介： 名稱： HRM-45DT型電動(dòng)表面洛氏硬度計(jì) 描述： 電動(dòng)式測(cè)試，試驗(yàn)力的施加、保荷和卸荷自動(dòng)完成。消除人為操作誤差，使用方便。其特點(diǎn)：試驗(yàn)力小，留下微小壓痕。 適用范圍 表面淬火鋼，銅、鋁合金等薄板，硬質(zhì)合金鋼，鍍鋅，鍍鉻，鍍錫，材料表面熱處理和化學(xué)熱處理等。 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. 技術(shù)數(shù)據(jù)（Technical Specifications） 表面洛氏標(biāo)尺(Superficial Rockwell Scales): HR15N, HR30N, HR45N, HR15T, HR30T, HR45T 試驗(yàn)力（Initial Testing Force）: 29.42N(3Kg) 試驗(yàn)力（All Testing Force）: 1471.1N(15Kg),294.2N(30Kg),441.3N(45Kg) 硬度讀取(Indication of Hardness Value): 表盤式（Dial ） 保菏時(shí)間(Duration Time): 2 ~ 60S 試件最大高度Max.
