Model
HVS-10 Digital Low Load Vickers Hardness Tester HVS-10型数显小负荷维氏硬度计是光机电一体化的高新技术产品，具有良好的可靠性，可操作性，是小负荷维氏硬度计的升级换代产品。
该机采用计算机软件编程，高倍率光学测量系统，光电传感等技术，通过软键输入，能调节测量光源的强弱，选择测试方法与对照表、保持时间、文件号与储存等，在LCD大屏幕显示上能显示试验方法、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，并通过RS232接口与计算机连网。
硬度计可选摄影装置，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。
Low
Load Vicker’s
Hardness Tester with Digital Display is a new hi-tech product integrating mechanical
and photoelectrical technologies. As a substitute of traditional small-load Vicker’s hardness tester,
it features in easy operation and good reliability.
The following highlight some key features and functions:
--Integration of computer programming technology, high resolution
optical measuring system and hotoelectrical technique;
--Soft key input;
--Light source adjustment;
--Selectable testing model, conversion tables, pressure-holding
time, file number input and data saving functions;
--Big LCD screen to display testing model, testing pressure,
indention length, hardness values, pressure holding time and numbers of tests;
--Date recording test results recording and data processing;
--Printing output function;
--RS232 interface for PC connection;
--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 hardness testing instrument for research or measuring purposes.
