How to choose a suitable Leeb hardness tester for yourself
① Understand the specifications of the workpiece you need to test, as well as its physical properties such as size, thickness, and surface roughness.
② The material of the workpiece can also have different effects on the test results, such as special materials such as aluminum, copper, tool steel, etc. The rebound modulus of different materials is different, and the choice of impulse device is extremely important for the test results.
③ The purpose of purchasing the Leeb hardness tester is to test the hardness system, HL、HB、HRC、HRB、HV、HS， If you meet the above conditions, you can purchase a Leeb hardness tester that can improve your work efficiency.

Leeb hardness testerCalibration: Due to its convenient portability, simple operation, rapid detection, and accurate measurement, it has been widely used in various work fields worldwide. Due to people's habits and the long-standing hardness measurement standards, the commonly used hardness testing methods in practice are still Brinell, Rockwell, Vickers, and Shore hardness testing methods. The Leeb hardness test method only appeared in the past 20 years, and it will take some time to directly use the Leeb hardness test method for hardness testing. At present, in order to balance the practicality of the Leeb hardness tester with the requirements of traditional hardness measurement standards and meet the needs of hardness testing work, people often need to convert Leeb hardness values into Brinell, Shore, Rockwell, Vickers and other hardness values. Whether the Leeb hardness value can be directly converted into other hardness values depends on the impact device used and the hardness material being tested. Establishing the conversion relationship between different hardness values often requires a lot of work from people.
The standard of Leeb hardness tester: Due to its characteristics of easy portability, simple operation, rapid detection, and accurate measurement, it has been widely used in the detection of metal hardness. Relevant national departments have also issued a series of standards for Leeb hardness tester. The following will briefly introduce them.

The conversion data between Leeb hardness and strength included in the Leeb hardness tester is based on the national standard, and the Leeb hardness tester has the following characteristics:;
① The impact device has interchangeability. The main unit of the Leeb hardness tester can be equipped with seven different types of impact devices simultaneously; Several impact devices of the same type can be configured on a single host.
② The punch of the impact device is replaceable. The punch of the Leeb hardness tester impact device is replaceable. The punches of the same type of impact device can be replaced with each other without affecting the value.
③ Not adjustable. The Leeb hardness tester does not have adjustability after leaving the factory. If the measurement value is inaccurate due to the wear of the ball head, the solution should be to replace the ball head.
④ The measurement error meets the standard requirements across the entire range of hardness. The measurement error of the Leeb hardness tester meets the error requirements specified by the standard throughout the entire range of hardness, from low to high.
