The Leeb hardness tester is a kind of testing equipment. The basic principle is that an impact body with a certain mass impacts the surface of the sample under a certain test force, and the impact speed and rebound speed of the impact body 1mm away from the sample surface are measured. Using electromagnetic Principle, induction of voltage proportional to speed.
The Leeb hardness tester of Asia Test (Shanghai) Instrument Technology Co., Ltd. is a new type of portable hardness testing instrument. It is mainly suitable for testing the hardness of metal materials. It has high testing accuracy, small size, easy operation, portability, and wide measurement range. Its characteristics are based on Leeb hardness as the principle. The measured Leeb (HL) hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the program. It can also be configured with various test accessories to Suitable for various testing conditions and environments, it is mainly suitable for rapid hardness testing of metal materials, especially suitable for on-site hardness testing of large parts and non-detachable parts.
Calibration method of Leeb hardness tester: 1. Press and hold the "hardness" key, and then press the on/off key; 2. The letter "U" is displayed at the bottom of the screen; 3. Measure 5 times on the standard block; 4. Press "Confirm/Average" Press key twice; 5. Enter the value on the standard block; 6. Press "Confirm/Average" again, it will automatically shut down; 7. Calibration is successful.
