Overview
LEEB leeb140 Leeb hardness tester is a multi-functional Richter Hardness measuring instrument with built-in high-speed thermal printer, which can set tolerances and comes standard with D-type Impact device. Miscellaneous Impact device can be purchased according to needs. Replacement of Impact device does not require calibrate, and has automatic identification function. The hardness gauge adopts a full Chinese display screen and menu operation, which is simple and convenient. It can directly display various Hardness values such as Richter, Brinell, Rockwell, Vickers, and Shaw. It is compact and easy to carry.
Features
1. Standard D-Impact Device
2. According to the Richter Hardness Measurement principle design, can be Richter, Rockwell, Brinell three kinds of calibrating, boot display Rockwell measurement interface
3. Interchangeable Hardness and tensile strength
4. One host can be equipped with 7 different Impact devices, no need to calibrate when replacing, automatic identification
5. Use standard rockwell hardness test blocks to save costs
6. Measured value, Impact direction, number of tests, test material, average value, date, Hardness system and other information can be displayed
7. Built-in thermal printer, support on-site real-time printing to ensure the fairness of measurement results and long-term storage and traceability of data
8. Test date and code can be entered
9. With automatic shutdown function and indication Adjustment
10. With charging indication and low voltage alarm function
Principle
According to the Richter Hardness Measurement principle, the material surface is impacted by the Impact device, and the ratio of the rebound speed to the Impact speed is measured to calculate the Richter Hardness value, which can be automatically converted into Miscellaneous Hardness standards such as Brinell, Rockwell, Vickers, and Shaw.
Applications
Mold cavities, heavy workpieces, installed machinery or permanent assembly parts, Pressure Vessels, turbo-generator sets and their equipment failure analysis, workpieces with small measurement space, bearings and other parts, large workpieces Quick inspection of multiple measurement parts in a wide range, material distinction in metal material warehouses
Steps
1. Turn it on and display the Rockwell measurement interface.
2. Select the appropriate Impact Device and install it
3. Set up test parameters and materials
4. Hardness measurement
5. View measurement results and statistics
6. Optional on-site printing of measurement data
7. Automatic shutdown after use
Notice
• When testing gear Hardness, if the gear is too small, you need to choose DL Impact device
• When testing castings, if the surface finish is difficult, you need to choose a G-type Impact device
• Hardness testing for heat treatment such as annealing, tempering, and quenching. If there is a hardened layer during selection, 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.
• When testing the bearing Hardness, you need to pay attention to its bearing diameter. If the diameter is too small, you need to choose a special-shaped support ring.
• The instrument has gray and black Color shell, the user can choose one of them
