VC-5A1維氏硬度計（手動轉塔）
VC-5A1 Vicker's Hardness Tester

VC-5A1維氏硬度計采用精密機械技術和光電技術的新型維氏硬度計。
　　該機內置硬度計算器，可通過輸入壓痕對角線長度，直接在LCD屏幕上顯示硬度值。試驗力保持時間，以LCD顯示。測量系統采用獨特的測微目鏡一次測量讀數機構，使用方便，測量精度高。
　　硬度計配可選攝影裝置，能對所測壓痕和材料金相組織進行拍攝，適用于測量微小、薄形試件、表面滲鍍處理后的零件，是科研機構、工廠及質檢部門進行研究和檢測的理想的硬度測試儀器。
     　　Vicker's Low Load Hardness Tester Model VC-5A1 is a new hi-tech product integrating precision mechanical and photoelectrical technologies.
The following highlight some key features and functions of this tester:
--Micro computer control;
--Adjustment of lighting source via soft keys;
--Adjustment of pressure holding time and LED display;
--Unique measurement conversion device and unique micro eyepiece one-time measurement readout device, ensuring easy use and high accuracy;
--Camera for indention photographing and metallography
The tester is specially designed for testing minute, thin samples or parts after surface coating.  For research institutes, factories labs and QC departments, this is an ideal harness testing instrument for research or measuring purposes
