Overview
DUBAN DB22-HM450 Leeb hardness tester is a portable hardness testing instrument. It is based on the electromagnetic induction principle of impacting the surface of the specimen under the action of the test force and measuring Impact and rebound speed. It is suitable for Hardness testing of various metal materials.
Features
1. Conversion between six Hardness (HL/HRC/HRB/HB/HV/HS) can be realized
2. Various test results can be displayed repeatedly, and the largest errors can be removed
3. Test materials and test methods can be selected through the keyboard
4. Use "USB data cable output" and "RS-232 data cable output" to communicate with PC
5. Provide "Bluetooth Bluetooth ™ data output" selection
Principle
The basic principle of Leeb hardness tester is that a certain mass of Impact body impacts the surface of the sample under a certain test force, and the measurement of Impact speed and bounce speed at 1mm from the surface of the sample.
Applications
Failure analysis of installed machinery or permanent assembly parts, die rows, heavy workpieces, Pressure Vessels and turbo-generator sets and their equipment, workpieces with small experimental space, bearings and other parts, requiring formal original records of test results, material differentiation in metal material warehouses and rapid inspection of multiple measurement parts of large-scale work
Steps
1. Select the test material and test method through the keyboard
2. Align the Impact Device to the specimen surface for testing
3. Review and confirm test results
4. Data can be transferred to PC via data cable or Bluetooth
