產(chǎn)品簡介：

名稱： hv-1000型顯微硬度計

描述： 采用lcd顯示屏，通過操作控制鍵可選擇硬度標尺hv或hk、試驗力、保荷時間、光源亮度可以無級調(diào)節(jié)。用測微目鏡測得對角線長度d1和d2值，按鍵輸入后即可在lcd上顯示硬度值，操作簡便。

適用范圍

熱處理、碳化、淬火硬化層，表面覆層，鋼，有色金屬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
