VC-5A1维氏硬度计（手动转塔）
VC-5A1 Vicker's Hardness Tester

VC-5A1维氏硬度计采用精密机械技术和光电技术的新型维氏硬度计。
　　该机内置硬度计算器，可通过输入压痕对角线长度，直接在LCD屏幕上显示硬度值。试验力保持时间，以LCD显示。测量系统采用独特的测微目镜一次测量读数机构，使用方便，测量精度高。
　　硬度计配可选摄影装置，能对所测压痕和材料金相组织进行拍摄，适用于测量微小、薄形试件、表面渗镀处理后的零件，是科研机构、工厂及质检部门进行研究和检测的理想的硬度测试仪器。
     　　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
