This instrument is widely used in such fields as metallurgy, electro-mechanics and mould, etc. It can analyze and measure the hardness value of specimen or surface hardened layers, hence it is an absolutely indipensable instrument for analysis and test in the field of mechanics machining or measurement of high precision parts. By means of RS232 interface to connect with computer, move X axis and Y axis with different step length selected, automatic focusing by Z axis, the instrument is specially fit to measure the hardness value of carburized layer of specimen or the depth of hardeded layer. Applying with different loads, different kinds of specimens can be tested. And it can form and store the graph-text reports. It is simple to operate and easy to use for clients.
This software can control such operations of hardness tester as: rotation of motorized turret, light luminosity, dwell time, movement of loading table, application of loading and automatic focusing, etc, it can enable the PC computer to control the hardness tester with command as well. At the same time, the hardness tester can feedback the information of command executed. It enables all the connecting units to communicate with each other. With friendly user interface, humanization, stability, reliability and very high precision position of mechanics, this software will completely meet the needs of test requirements.
This instrument can not only test single-point of Vickers hardness indentation, but also can test continuous multi-point of Vickers hardness indentations after automatically loadings. And it can make out the curve of hardness distribution as well. Accordingly to this curve, the accordance depth of hardened layer can be calculated out. All the measuring data, calculating results and indentation images may form graph-text reports which can be printed out or stored.
