The hardness tester is a hardness testing instrument,indicating the ability of the material to resist the hard object pressed into its surface,then you know the hardness tester has several kinds of it?

1,Brinell hardness tester:mainly used for cast iron,steel,non-ferrous metals and soft alloys and other materials,hardness determination,can reflect the comprehensive performance of the material,is not subject to the specimen organization micro segregation and composition of the unevenness of the impact,so it is a higher precision hardness test method.

2,rockwell hardness tester:one-sided contact specimen can test the hardness of metal rockwell hardness tester,relying on magnetic force will rockwell hardness tester head adsorption on the surface of steel,do not need to support the specimen!

3,Vickers hardness tester:Vickers hardness tester is an optoelectronic integration of high-tech products,the machine has a novel shape,with good reliability,operability and intuition,is the use of precision mechanical technology and optoelectronic technology of the new type of Vickers and Nup hardness testing instruments.

4、Brockwell hardness tester:the brockwell hardness tester is suitable for ferrous metals,non-ferrous metals,cemented carbide,carburizing layer and chemical treatment layer hardness determination.

5,micro hardness tester:micro hardness tester is machinery,metallurgy and other industries to carry out metal material properties test precision instruments,widely used in various industries.

6,Richter hardness tester:its basic principle is to have a certain quality of impact body in a certain test force under the action of impact on the surface of the specimen,measuring the impact of the impact body from the surface of the specimen 1mm at the speed of impact and jump back speed,the use of electromagnetic principle,induction and speed proportional to the voltage.

7,Wechsler hardness tester:Wechsler hardness tester principle of a certain shape of hard steel pressure needle,under the action of the standard spring test force pressed into the specimen surface.

8,bartholomew hardness tester:is a kind of indentation hardness tester,it is a specific indenter in the standard spring force under the action of pressing into the specimen,to the depth of the indentation to determine the hardness of the specimen.

How to identify the advantages and disadvantages of the Richter hardness tester?

Richter hardness tester is a test equipment,its basic principle is to have a certain quality of impact body under the action of a certain test force can impact the surface of the specimen,measuring the impact body from the surface of the specimen 1mm at the impact speed and jump back speed,you can utilize the electromagnetic principle,the induction and the speed of the proportional voltage.Different manufacturers of the Richter hardness tester in the quality is certainly there will be some differences,specifically how to determine the advantages and disadvantages of the Richter hardness tester,we can be determined by the following methods.
