HVD系列程控数显维氏硬度计有六种型号:分别为10kg手动及自动转塔维氏硬度计、30kg手动及自动转塔维氏硬度计、50kg手动及自动转塔维氏硬度计，是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D型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，并选择维氏与努氏试验方法、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。
该硬度计应用范围广，即适用于测量微小、薄形及表面渗镀层处理后的零件，也适用于一般机械零件测试，显微维氏硬度试验更能进行材料金相组织及脆性材料的硬度测量。是工厂及质检部门进行研究测试的理想的硬度测试仪器。
HVD Series program-controlled Vickers hardness have six models: respectively for 10 kg the manual and automatic Vicker's hardness tester, 30 kg manual and automatic Vicker's hardness tester, 50 kg manual and automatic Vickers's Hardness tester, is use computer software controls,the high magnification optical measurement system and photoelectric sensor technology implementation the diagraph equips and indenter automatically conversion,passing the software input,the strong or weak of the light source regulates automatically and choose Vckers's and Knoop's test、dwell time,document number and storage etc.,Offers a variety of hardness value of the conversion table for reference,In large-screen LCD screen can display test methods, test force, and measuring the length of indentation, hardness, test dwell time, measuring number and input year,month,date,experimenting the result handles with data etc.,pass the printer exportation.
The tester is specially designed for testing minute, thin samples or parts after surface coatng or general mechanical part. For research institutes, factories labs and QC departments, Microscopic Vickers hardness test for better material microstructure and brittle hardness of measurement.this is an ideal hardness testing instrument for research or measuring purposes.
