1. Choose imported or domestic Leeb hardness tester?
The Swiss company PROCEQ invented the Leeb hardness tester in 1977. The company's Leeb hardness tester is world-renowned. At present, many countries in the world use the company's technical standards as the national measurement standard, China's national measurement standard. It is also based on the technical standards of PROCEQ. The main feature of the Leeb hardness tester produced by Swiss PROCEQ is that one main unit can be equipped with seven different types of impact devices. The imported Leeb hardness tester is impeccable in performance, but the imported Leeb hardness tester is relatively expensive. The purchase of the imported D-type standard configuration of the Leeb hardness tester is about RMB 70,000, and the problem is not convenient for maintenance. . The domestic Leeb hardness tester is characterized by low price. The purchase of the domestic D-type standard configuration of the Leeb hardness tester is about RMB 10,000. However, the domestic Leeb hardness tester has advantages and disadvantages, and must be carefully selected when purchasing. Time Group is a domestic manufacturer of Leeb hardness testers. Since the R&D and production in 1978, the company has produced the Leeb hardness tester, Rockwell hardness tester, flaw detector, thermometer, thickness gauge and other non-destructive testing instruments in the world. Enjoy a high reputation, but also effectively reduce the cost of production for major domestic customers. The hardness tester produced by Time Company is in line with national standards and international standards and has interchangeability consistency. It is also a domestic enterprise that does not use the modified method to produce the Leeb hardness tester.
2. How to identify the pros and cons of the Leeb hardness tester?
The true Leeb hardness tester is in line with national and international standards and is interchangeable. Although the relevant Chinese authorities have established the national standard for the Leeb hardness tester, some manufacturers' technical strength is not up to the standard of the standard Leeb hardness tester. Therefore, the revised method is used to produce the Leeb hardness tester. The Leeb hardness tester, but far from the real Leeb hardness tester, the hardness tester with the original measurement error can also meet the exact requirements of the test hardness test block after correction, so the user should choose the good hardness tester. The following features of the true Leeb hardness tester:
1 Impact device is interchangeable. A mainframe of the Leeb hardness tester can be equipped with seven different types of impact devices at the same time; several impact devices of the same type can be configured on one mainframe.
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 measured value.
The 3 Leeb hardness tester does not have adjustability. The Leeb hardness tester does not have adjustability after leaving the factory. If the measured value is not accurate due to the wear of the ball head, it should be solved by replacing the ball head.
4 Leeb hardness tester measurement error meets the standard requirements in the full range of hardness. The measurement error of the Leeb hardness tester in the entire range of hardness from low to high meets the error requirements of the standard.
