Digital Vickers Hardness Tester MHVS-30

Mitech MHVS series digital 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 digital display and 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. 

• 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

Micro-Vickers (or Knoop) hardness test principle is that put the provisions of the positive pyramid diamond indenter into the sample surface(with fixed experimental force) and maintain a certain length (holding), and then unloading. Finally, there is a positive quadrangular pyramid or kenup indentation with a square surface on the surface of the specimen. Then we can attain the area of indentation via measuring the length of the diagonal by a micrometer eyepiece. Then the corresponding Vickers (or Knoop) hardness values are obtained.

Widely used in micro-specimen, thin specimen, surface coating, heat treatment of workpiece surface samples and etc.
