| ZH5190型电动表面洛氏硬度计 |               |                              产品简介              电动表面洛氏硬度计是一种通过电动加载、保荷卸荷的半自动测试金属材料表面硬度的洛氏硬度计。具有操作简便、压痕微小、精度高等特点。             适用范围             表面淬火钢,铜、铝合金薄板,带钢,硬质合金钢,镀锌,镀铬,镀锡,材料表面热处理和化学表面处理的种金属材料。             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.             数据(Technical Specifications)                                                                        |                          表面洛氏标尺                         (Superficial Rockwell Scales)                          |                                                  HR15N, HR30N, HR45N, HR15T, HR30T, HR45T                                                    |                                                                  |                          初试验力(Initial Testing Force)                          |                                                  3Kg(29.42N)                          |                                                                  |                          试验力(All Testing Force)                          |                                                  15Kg(147.1N),30Kg(294.2N),45Kg(441.3N)                          |                                                                  |                          硬度读取                         (Indication of Hardness Value)                          |                                                  表盘式(Dial )                          |                                                                  |                          保菏时间(Duration Time)                          |                                                  2 ~ 60S                          |                                                                  |                          试件zui大高度                         Max.
