HVD-5A1型（手动转塔）数显维氏硬度计/HVD-5D1（自动转塔）数显维氏硬度计是光机电一体化的产品，该仪器造型新颖、美观，而且它具有良好的可靠性，可操作性和直观性，是显微硬度计的升级换代产品。   

    该机采用计算机软件控制，高倍率光学测量系统，光电传感等技术实现测量装置与压头自动切换，通过软件输入，光源的强弱自动调节，并选择维氏与克氏试验方法、保持时间，文件号与储存等，提供了各种硬度值的转换表以供参考，在LCD大屏幕显示屏上能显示试验方法，试验力，测量压痕长度、硬度值、试验力保持时间，测量次数并能键入年、月、日期，试验结果和数据处理等，通过打印机输出。   

    该机可测定钢、有色金属、IC薄片、薄塑料、金属薄片、涂层、表面覆层、层压金属、热处理碳化层和淬火硬化层的深度与硬度梯度。

    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.
