Overview
LEEB U910 Portable Leeb hardness tester is a Portable Hardness tester with full Chinese display and menu operation. The instrument can directly display a variety of Hardness values such as Richter, Brinell, Rockwell, Vickers, Shaw, etc. It has the characteristics of small portability and high Reliability. It can adapt to harsh operating environments and has the ability to resist vibration, Impact and electromagnetic interference.
Features
1. According to the Richter Hardness Measurement principle, the Richter HL measurement interface is displayed when turned on, which can perform High Accuracy detection on a variety of metal materials.
2. Support "forged steel (Steel) " material, and the HB value can be directly read when testing with D/DC type Impact device, without manual table checking.
3. It is convenient to switch to all Hardness formats (HL, HB, HRB, HRC, HV, HS), and convert each Hardness measurement value in parallel.
4. Graphical point matrix LCD screen, rich in information and intuitive.
5. Full Chinese display, menu operation, simple and convenient operation.
6. Equipped with high-brightness LED backlight display, it is convenient to use in the gray environment of light rays.
7. One mainframe can be equipped with 5 different Impact devices (D, G, C, DL, DC) to automatically identify the type of Impact device, and there is no need to re-calibrate when replacing.
8. It can store up to 600 sets (Impact times 30~ 1) Hardness measurement data, each set of data contains single Measured value, average value, measurement date, Impact direction, number of times, material, Hardness system and other information.
9. The upper and lower limits of Hardness value can be preset, and the automatic alarm beyond the range is convenient for batch testing.
10. Powered by 2 alkaline batteries, with power-saving functions such as automatic shutdown.
11. The LCD screen has a remaining power indicator icon, prompting the user to replace the battery in time.
12. Adjustment of indication software.
Principle
The instrument works according to the Richter Hardness Measurement principle. After booting, it directly enters the Richter HL measurement interface, applies Impact to the surface of the metal material through the Impact device, measures the ratio of the rebound speed of the Impact body to the Impact speed, and then calculates the Richter Hardness value. It can be converted into various Miscellaneous Hardness standards in parallel through the built-in program.
Applications
Installed machinery or permanent assembly parts, mold cavities, heavy workpieces, workpieces with small measurement space, Pressure Vessel, failure analysis of turbine generator sets and their equipment, bearings and other parts, material differentiation of metal material warehouses, large workpieces Quick inspection of multiple measurement parts in a wide range
Notice
1. When used for Hardness testing of products in mass production, the standard set can generally meet the testing requirements.
2. Hardness testing for annealing, tempering, quenching and other heat treatments should pay attention to the thickness of the hardened layer when selecting the type. If the hardened layer is too thin, the C-type Impact device needs to be selected.
3. When used to detect bearing Hardness, pay attention to its bearing diameter. If the diameter is too small, you need to choose a special-shaped support ring.
4. When used for gear Hardness detection, if the gear is too small, choose the DL Impact device.
5. When used for casting inspection, if the surface finish treatment is difficult, a G-type Impact device needs to be selected.
