Model HVS-50 Digital Low Load Vickers Hardness Tester
I. Application:
Low Load Vickers Hardness Tester with Digital Display is a new hi-tech product integrating mechanical and photoelectrical technologies. As a substitute of traditional small-load Vickers 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 photoelectrical 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.
