Overview
The Portable Leeb hardness tester U913 is an innovative true color screen hardness gauge based on the Richter Hardness Measurement principle. It adds four hardness of materials to the existing data table and develops the "User Materials" function to meet the testing needs of special materials, significantly expanding the scope of use. The instrument can be designed and manufactured according to customer needs Impact devices and tooling fixtures.
Features
1. According to the Richter Hardness Measurement principle, all metal materials can be tested for High Accuracy.
2. Added four kinds of hardness of materials, and has the function of "user material", theoretically can test the hardness of all metal materials.
3. Easy to switch to all Hardness formats (HL, HB, HRB, HRC, HRA, HV, HS), and convert each Hardness measurement value in parallel.
4. Adopt large-screen true-color LCD display and WOINDOWS interface, providing clear and intuitive information.
5. Menu operation, simple and convenient, can adjust the LCD luminance arbitrarily.
6. Equipped with USB communication interface, it is convenient to exchange data and set parameters with PC.
7. One main engine can be equipped with 7 different impact devices, automatically identifying the type of impact device, and no need to re-calibrate when replacing.
8. Can store up to 600 sets of Hardness measurement data, each set of data information is complete.
9. The upper and lower limits of Hardness value can be preset, and the automatic alarm will be issued if the range is exceeded.
10. Adopt plastic alloy shell, anti-vibration, Impact and electromagnetic interference, suitable for harsh environment.
11. The power supply uses an integrated lithium battery, which can operate continuously for at least 100 hours and has a power-saving function.
12. There is a remaining power indicator icon on the LCD.
13. Adjustment of indication software.
14. It can be equipped with powerful microcomputer software to meet the higher requirements of mass assurance activities and management.
Principle
The product works based on the Richter Hardness Measurement principle. Impact is applied to the material surface through the Impact device, and the ratio of the rebound velocity of the Impact body to the Impact velocity at a distance of 1mm from the specimen surface is measured to calculate the Richter Hardness value. According to the built-in data table and user-defined material parameters, it can be converted to various Miscellaneous Hardness formats in parallel.
Applications
Mold cavities, cores, bearings and other parts, Pressure Vessels, failure analysis of turbo-generators and their equipment, heavy workpieces, installed machinery or permanent assembly parts, workpieces with very small Test space, occasions requiring formal original records of test results, material differentiation in metal material warehouses, rapid inspection of large workpieces in a wide range of measurement parts
Standards
"Leeb hardness tester technical conditions" JB/T 9378-2001
Steps
1. Select the appropriate Impact device according to the tested material and install it.
2. Turn it on and select or set relevant parameters (such as material, Hardness standard, upper and lower limits, etc.) through the menu.
3. Press the Impact device vertically on the surface of the workpiece to be tested, and press the Impact button for measurement.
4. Read or store measurement results.
5. It can be connected to the PC through the USB interface for data transmission or parameter setting.
Notice
* Impact device type is correct and firmly installed before measurement.
* Impact direction should be perpendicular to the measured surface during measurement.
* The instrument is used at 0-40 ℃ Ambient Temperature.
Pay attention to the power indicator on the LCD screen and charge it in time.
* For special materials, it is recommended to calibrate or test using the User Materials feature.
The instrument shell is made of plastic alloy, which has high strength but still needs to be avoided from severe impact.
* When the preset Hardness value range is exceeded, the instrument will alarm, please pay attention to the identification.
