產品簡介
數顯顯微硬度計采用大顯示屏LCD顯示，界面操作采用菜單式結構，可在操作面板上選擇硬度標尺HV或HK，通過數碼測量壓痕，自動輸入，自動顯示硬度值。并可進行**硬度值相互轉換，測試結果可自動儲存、處理、打印。備有RS-232接口，可與計算機聯機。本機數字化、自動化程度較高。
適用范圍
熱處理、碳化、淬火硬化層，表面覆層，鋼，有色金屬，微小及薄形零件等。
Digital Micro Vickers Hardness Tester adopts large LCD screen to display and menu type structure to choice hardness scales HV or HK, exchange hardness values among scales, store testing results and data procession automatically, as well as output by printer. By means of interface of RS-232, the instrument can be linked with computer.
Usage Range:
Heat treated layer, carbonized layer, hardened hard layers, superficial coating, steels, n-ferrous metal, micro and thin shaped components.
