本系列視屏測量顯微硬度計是在顯微硬度計上，通過CCD彩色攝像頭光學接口，直接能在顯示屏上測量完成。增加了測試的速度和靈活性，提高了測量精度，體現(xiàn)了像質(zhì)的清晰度，減少了目鏡系統(tǒng)人為的操作誤差，能滿足各種顯微硬度測試要求。

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。

This design is based on HVS-series vickers hardness tester, added with CCD camera.15" TV which shows the measured picture. increased the accuracy of the measurement, shows the clear view of picture and decrease the error due to the human operation .therefore upon the release .it is welcomed by the university, science unit state and private owned enterprises. as well as foreign company.

Usage Range:
Heat treated layer, carbonized layer, hardened hard layers, superficial coating, steels, non-ferrous metal, micro and thin shaped components.
