[Webster Hardness Tester W-20 Product details]:
Product Specification:

• Models for testing brass, copper and mild steel respectively；
• Modification models for testing thick pieces or slim tubings;
• Tests sheets, extrusions, pipes;
• Very fast, very simple and very portable;
• Small indentation;
• Conforms to ASTM B647;
• Recommended in YS/T420;
 
Introduction, 
• Webster Hardness tester is a kind of hardness testing machine which is specialized in testing the hardness of the aluminum alloy on site rapidly;
• It pressed a certain shape of hard steel pressure needle into the surface of the sample;
• The webster hardness of the material can be read directly according to indentation depth;
• The hardness values can be converted into other types of hardness values which includes Vickers, Rockwell and Brinell;
 
• Different models of instruments can be made when Webster hardness testing equipment applies different sizes of pressure needles and different testing force.
• All of these models can be applied in aluminum, brass tube, copper tube and stainless steel strip or cold-rolled strip and other materials.
 
• In addition, Webster Hardness testing machine is also suitable to test the material with two parallel surfaces such as tubes, plates and profiles, the maximum thickness of the material can reach 13mm.
• The Webster hardness tester adopts high-pressure needles and high strength pointers with new materials and new technologies, thus it is not easy to be out of shape in the long-term use or incorrect operation, which ensures stable and accurate testing results.
 
• Webster Hardness is compact and light and weighs 0.5kg and it carries out non-destructive test with single-hand rapid operation.
• Users do not need to take samples in the testing process and can grasp the operational skills easily.
 
• Our product is very suitable for production site, sales site and construction site and can test the qualification of the bulk products without destruction one by one rapidly.
• It becomes the preferred instrument in testing the mechanical properties of aluminum extrusions.
 
Features ,
• This Webster hardness tester is a portable testing instrument and could quickly test the hardness of aluminum alloy and other soft metal on site.
• It is in accord with the ASTM B647 standard.
• It is used to test the heat treating effect of materials and determine whether the alloy composition of material is qualified or not.
•  It is used to test the hardness of soft metals, pipes, plates and other parts.
• This portable hardness tester can be used to test extra long, extra heavy workpieces or assembly parts which are not convenient to be sent into the laboratory.
• It is especially suitable for testing the bench production, piece by piece on site.
• Made from anodized, forged Al alloy, the upper hand handle is beautiful, wear resistant and pollution free.
• The hardness indenter adopts new material and new technology, and features high hardness and long service life.
•  Different models available for testing aluminum alloy, brass, copper alloy and copper.
