HVD-5A1型（手動轉塔）數顯維氏硬度計/HVD-5D1（自動轉塔）數顯維氏硬度計是光機電一體化的產品，該儀器造型新穎、美觀，而且它具有良好的可靠性，可操作性和直觀性，是顯微硬度計的升級換代產品。   

    該機采用計算機軟件控制，高倍率光學測量系統，光電傳感等技術實現測量裝置與壓頭自動切換，通過軟件輸入，光源的強弱自動調節，并選擇維氏與克氏試驗方法、保持時間，文件號與儲存等，提供了各種硬度值的轉換表以供參考，在LCD大屏幕顯示屏上能顯示試驗方法，試驗力，測量壓痕長度、硬度值、試驗力保持時間，測量次數并能鍵入年、月、日期，試驗結果和數據處理等，通過打印機輸出。   

    該機可測定鋼、有色金屬、IC薄片、薄塑料、金屬薄片、涂層、表面覆層、層壓金屬、熱處理碳化層和淬火硬化層的深度與硬度梯度。

    The HVD-5A1/HVD-5D1 type counts to show it is high and new technique product that light machine electricity integral whole turn that degree of hardness account,the instrument's shape is novel,beautiful,ａnd it have the good and dependable,maneuverability with keep the view,is a grade creep to show minute details degree of hardness account to change the on behalf product.     

    The machine's adoption calculator software controls,the high magnification optics measures the system,the light fax feels the etc.Technique realizes the diagraph equips with press a cuts over automatically,passing the software importion,the strong or weak of the light source regulates automatically and choose the surname of experiments with gram surname the method and keeps time, document number and storage etc.,Provide the worth conversion in every kind of degree of hardness form toes provide to consult,can show to experiment the method in LCD ising big to hold act showing holding,experimenting the dint,measuring to press the length of,degree of hardness the value and experiment the dint keeps time,measure the number of times combine it can key- in the year, month,date,experimenting the result handles with data etc.,pass the printer exportation.

   That machine can measurese the steel,have the color metals,the thin slice of IC,thin plastics, metals thin slice and draw the layer,surface layer,layer presses the metals,heat handles the carbonization layer hardens the depth of the layer with the fire of and degree of hardness steps degree.
