Libo leeb140 Leeb Hardness Tester is a multifunctional Leeb hardness measuring instrument with a built-in high-speed thermal printer. Tolerance can be set. It is equipped with a D-type impact device as standard. Other impact devices can be purchased according to actual needs. It is not necessary to replace the impact device. Calibration, with automatic identification function.
Leeb140 Leeb Hardness Tester adopts a full Chinese display screen, menu-style operation, simple and convenient, and can directly display various hardness values such as Leeb, Brinell, Rockwell, Vickers, and Shore. Small size, easy to carry.
1) Mold cavity.
2) Heavy workpieces.
3) Installed mechanical or permanent assembly parts.
4) Failure analysis of pressure vessels, turbogenerators and their equipment.
5) Measure workpieces with very narrow space.
6) Bearings and other parts.
7) Rapid inspection of multiple measuring parts in a large range of large workpieces.
8) Material classification of metal material warehouse.
1. Leeb140 Leeb Hardness Tester is equipped with D-type impact device as standard.
2. Designed according to the principle of Leeb hardness measurement, it can perform three calibrations of Leeb, Rockwell, and Brinell, and the Rockwell measurement interface will be displayed when the machine is turned on.
3. The hardness and tensile strength can be converted to each other.
4. One leeb140 Leeb Hardness Tester host can be equipped with 7 different impact devices for use, no calibration is required for replacement, and automatic identification is required.
5. Use standard Rockwell hardness test blocks to save costs.
6. It can display the measured value, impact direction, test times, test material, average value, date, hardness system and other information.
7. The built-in thermal printer supports on-site instant printing to ensure the fairness of the measurement results and the long-term storage and traceability of the data.
8. You can input the test date and code.
9. It has the function of automatic shutdown and indication calibration.
10. The Leeb Hardness Tester has charging indication and low Voltage alarm function.





Note: Leeb140 Leeb Hardness Tester has gray and black shells, users can choose one of them.
1. When testing gear hardness, if the gear is too small, you need to choose DL impact device.
2. When testing castings, if it is difficult to express the smoothness, you need to choose the G-type impact device.
3. For the hardness testing of products in the process of mass production, generally a standard set can meet the testing requirements.
4. For hardness testing of annealing, tempering, quenching and other heat treatments, if there is a hardened layer, you need to pay attention to the thickness of the hardened layer. If the hardened layer is too thin, you need to choose a C-type impact device.
5. When testing the hardness of the bearing, it is necessary to pay attention to the bearing diameter. If the diameter is too small, it is necessary to select a special-shaped support ring.
