    HVD系列程控數顯維氏硬度計有六種型號:分別為10kg手動及自動轉塔維氏硬度計、30kg手動及自動轉塔維氏硬度計、50kg手動及自動轉塔維氏硬度計，是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D型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，并選擇維氏與努氏試驗方法、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。

    該硬度計應用范圍廣，即適用于測量微小、薄形及表面滲鍍層處理后的零件，也適用于一般機械零件測試，顯微維氏硬度試驗更能進行材料金相組織及脆性材料的硬度測量。是工廠及質檢部門進行研究測試的理想的硬度測試儀器。

    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.
