Overview
LEEB Leeb hardness tester leeb180D is a portable hardness testing instrument with full Chinese display and menu operation. The instrument can directly display a variety of Hardness values such as Richter, Brinell, Rockwell, Vickers, Xiao, etc. It is equipped with high-luminance LED backlight for easy use in environments with insufficient rays of light. It has power-saving functions such as automatic sleep and automatic shutdown. It is powered by lithium batteries and is suitable for on-site field operations. It has the characteristics of small portability and high test accuracy.
Features
1. Full Chinese display, menu operation, simple and convenient
2. Directly display Richter, Brinell, Rockwell, Vickers, Shaw and other Hardness values
3. High luminance LED backlight, suitable for gray environment of light rays
4. Automatic sleep, automatic shutdown and other power-saving functions, low-power design
5. Powered by lithium battery, it can work continuously for 10 hours
6. Compact and portable, high test accuracy
360 ° measurement direction, support a variety of Hardness standards
8. 600 sets of data storage functions
Principle
According to the Richter Hardness Measurement principle, the Richter measurement interface is displayed when turned on. The instrument calculates the Hardness value by impacting the surface of the sample through the Impact device, measuring Impact and rebound speed.
Applications
Installed machinery or permanent assembly parts, mold cavities, heavy workpieces, Pressure Vessels, turbo-generator sets and their equipment failure analysis, measurement space is very small workpieces, bearings and other parts, metal material warehouse material distinction, large workpieces in a wide range of measurement parts inspection
Standards
GB/T 17394.1-2014 "Metallic Materials, Richter Hardness Test, Part 1: Test Methods", GB/T 17394.2-2012 "Metallic Materials, Richter Hardness Test, Part 2: Hardness gauge inspection and calibrate", GB/T 17394.3-2012 "Metallic Materials, Richter Hardness Test, Part 4: Calibration of Standard Hardness Blocks", GB/T 17394.4-2014 "Metallic Materials, Richter Hardness Test, Part 4: Standard Value Conversion Table", JB/T 9378-2001 "Leeb hardness tester technical conditions"
Steps
1. The Richter measurement interface is displayed when turned on.
2. Select the corresponding Measurement mode and parameters
3. Align the Impact device vertically to the specimen surface for testing
4. Read and record measurement results
5. The instrument supports 600 sets of data storage
Notice
• Sample surface temperature should be less than 120 ℃
• The surface roughness of the sample should not be too large, and the metal Gloss should be exposed and smooth without oil stains
• Specimens weighing 2-5kg need to be supported by objects to avoid deformation
• Support rings are required when the radius of curvature of the sample is less than 30mm (type D, DC, C, DL) or less than 50mm (type G)
• Film thickness and hardening depth should comply with the Impact Device Table
• Lightweight specimens need to be tightly coupled to a sturdy support
• Large area plates, long rods and other samples should be firmly supported on the back of the test point
The sample itself should be less than 30 Gauss magnetic
• Pay attention to the diameter when testing the bearing. If the diameter is too small, choose a special-shaped support ring.
