产品简介：

名称： hv-1000型显微硬度计

描述： 采用lcd显示屏，通过操作控制键可选择硬度标尺hv或hk、试验力、保荷时间、光源亮度可以无级调节。用测微目镜测得对角线长度d1和d2值，按键输入后即可在lcd上显示硬度值，操作简便。

适用范围

热处理、碳化、淬火硬化层，表面覆层，钢，有色金属和微小及薄形零件等。

hv-1000 micro vickers hardness tester adopts lcd screen to display. by mean of control keys, hv or hk hardness scales, testing force and duration time can be se-lected and brightness of light source can be adjusted without steps. with measuring microscope, it may test out the length values of diagonals d1 and d2, then press the keys to input the length values, and the hardness values will be displayed on the lcd screen. operation is easy.

usage range:

heat treated layer, carbonized layer, hardened hard layers, superficial coating, steels, non-ferrous metal, micro and thin shaped components
