What Functions Should a Good Leeb Hardness Tester Have?


Leeb hardness tester is a better instrument for measuring hardness in hardness tester. It is easy to carry, simple to operate, rapid detection and accurate measurement, etc. It is widely used in the work field.


Due to people's habits and the hardness measurement standards that have been used for many years, hardness test methods such as Brinell, Rockwell, Vickers, and Shore are still commonly used in the actual hardness test.


Ⅰ. How to choose a good Leeb hardness tester?


The Leeb hardness test method has only emerged in the past 20 years, and it will take time to conduct hardness tests using the Leeb hardness tester principle directly. At present, in order to take into account the practicality of the Leeb hardness tester and the requirements of traditional hardness measurement standards, to meet the needs of hardness testing work, people often have to convert the Leeb hardness tester value into Brinell, Shore, Rockwell and Vickers and other hardness values.


Whether the Leeb hardness value can be directly converted into other hardness values, which is related to the impact device used and the hardness material to be measured, the establishment of the conversion relationship between different hardness values often requires people to carry out a lot of work.


Leeb hardness tester belongs to the measurement and testing instruments, plays an important role in ensuring product quality and failure analysis, so choosing a good Leeb hardness tester is a key issue for the user.


The real Leeb hardness tester is in line with international standards and has interchangeable consistency. Although the Chinese authorities have developed a national standard for Leeb hardness tester, the technical strength of some manufacturers can not reach the level of production in line with the standard Leeb hardness tester.


Therefore, the production of Leeb hardness tester using the revised method, although its products are also called Leeb hardness tester, far from the real Leeb hardness tester, the original measurement value is not allowed hardness tester after correction can also reach the test hardness test block accurate requirements, so the user to choose Leeb hardness tester to need to pay attention to the following aspects.


Ⅱ. The real Leeb hardness tester needs to have the following characteristics


1. The impact device has interchangeability. Leeb hardness tester of a host can be configured at the same time seven different types of impact devices; a number of the same type of impact device can be configured in a host.


2. The impact device punch has interchangeability. The punch of the impact device of the Leeb hardness tester is replaceable. The same kind of impact device punch can be replaced without affecting the measurement value.


3. Leeb hardness tester does not have adjustability. The Leeb hardness tester does not have adjustability after leaving the factory, and when the measured value is not allowed due to the wear of the ball head, the solution should be to replace the ball head.


4. The Leeb hardness tester measurement error in the full range of hardness to meet the standard requirements. Leeb hardness tester measurement error in the whole range of hardness from low to high is to meet the standard error requirements.


5. The battery compartment in the Leeb hardness tester is best to replace the battery to extend the service life of the machine, the replacement battery is also convenient and practical like some manufacturers are the battery and the instrument as a whole, the battery is not a good lithium battery, so the battery of the Leeb hardness tester if bad, the instrument can not be used.


6. The Leeb hardness tester screen is a high-definition bright color large screen so that regardless of the working environment is dark or the viewing angle is not good, can clearly see the measurement value, to facilitate better work.
