Vickers hardness tester, based on the principle that positive quadrangular pyramid diamond indenter presses the surface of the sample to produce indentation.By measuring the diagonal length of the indentation to achieve the measurement of the hardness of the material can be for small specimens, thin specimens, surface coating, heat treatment of the workpiece surface Vickers hardness test. 

With stable performance, strong structure, high reliability, simple operation, adopt high magnification optical measurement system, adjust the cold light source, photoelectric sensing technology and computer-aided means it has a powerful function. 


It is widely used in the fields of metal processing, electronics industry, mold parts, watch manufacturing, engineering quality inspection and so on. It is an ideal hardness tester for material research and testing. 


Application:


Metal processing manufacturing quality control links

University education teaching demonstration experiment

Failure analysis test of metal material

Testing of material hardness of scientific research institutions

Quality inspection departments quality testing links



Features:


Widely used in micro-specimen, thin specimen, surface coating, heat treatment of workpiece surface samples and etc.Vickers hardness test to meet different demands of scientific research institutions, precision machining and quality inspection departments and other materials research;

Equipped with a variety of small load Vickers hardness scale spare;

Innovative, rugged construction, high reliability, easy to operation, intuitive reading, high efficiency;

Host performance is good, the workpiece surface quality and man-made factors have less impact on the hardness test results;

Adopt electronic automatic loading system to control the main test force, eliminating the need to load the weight, the operation more convenient;

Adopt large-screen LCD liquid crystal display, easy to operate, visually display the test results;

Using high-rate optical sensing system and high-precision photoelectric sensing  integrated high-tech product technology, greatly improving the test efficiency and accuracy;

Adopt diamond indenter, durable and accurate;

Adjustable cold light source measurement system that can control the light strength through the software;

Optional photographic device, can be achieved on the measured indentation and material microstructure to shoot for later analysis;

With ISO 6507, ASTM E92, JIS Z2244, GB/T4340.2 and other relevant domestic and foreign standards
