维氏|显微硬度计
显微硬度计是基本型的显微硬度计,该机采用LCD显示屏,通过操作面板可对硬度标尺HV或HK各档试验力保荷时间进行选择,光源亮度可作无级调节。
操作时,可将目镜测得的D1,D2值直接输入后,硬度值即在LCD显示屏上直接显示。
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 selected 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 ponents.
