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.

The real Richter hardness tester should be in line with national and international standards,and should have interchangeable consistency.Although the relevant departments of our country formulated the national standard of Richter hardness tester,but may be some manufacturers of technical strength is far from the production of standard Richter hardness tester level,so the use of correction method to the production of Richter hardness tester,although the product is also known as Richter hardness tester,but with the real Richter hardness tester in fact is far away,the original measurement of value is not allowed to the hardness tester in the correction is also can be Achieve the accurate requirements of the test hardness test piece,so users need to pay attention to when choosing the Richter hardness tester,high-quality Richter hardness tester should have the following characteristics:

(1)impact device punch should have replaceable.The same type of impact device punch can be realized to replace each other,but does not affect its measured value.

(2)The impact device is interchangeable.Richter hardness tester of a host should be able to do at the same time to configure seven different types of impact device;a number of the same type of impact device,should be able to configure in the same host.

(3)Richter hardness tester does not have adjustability.Richter hardness tester does not have adjustability after the factory,if the ball wear caused by the measurement value is not allowed,should be used to replace the ball approach to solve.

(4)Richter hardness tester measurement error in the full range of hardness should meet the standard requirements.Richter hardness tester measurement error in the hardness of the whole range,should be from low to high to meet the standard error requirements.

Richter hardness tester belongs to the measurement and testing instruments,in order to ensure product quality,failure analysis plays a very important role,so choose a good Richter hardness tester for the user is a very critical issue.
