LS251D Leeb hardness tester Introduction: The local resistance of a material to hard objects pressing into its surface is called hardness, which is an index to measure the hardness and softness of the material. LS251D Leeb hardness tester detects hardness according to Leeb hardness measurement principle, and can measure hardness of various metal materials. The instrument adopts advanced digital probe technology, and digital signal processing is directly completed on the probe. The probe is not easy to be disturbed and provides excellent test accuracy. The probe has a built-in direction sensor to automatically compensate the measurement error in different impact directions. A variety of hardness systems are built in the system, including Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) and tensile strength（ σ b) They can be converted from each other to avoid tedious manual calculation. The practical value of hardness testing with LS251D Leeb hardness tester lies in its incomparable portability - simple operation, convenient carrying and batch testing. characteristic: 1. Advanced digital probe technology is adopted, and digital signal processing is directly completed on the probe. The probe is not easy to be disturbed and provides excellent test accuracy. 2. The instrument can measure at 360 ° angles. The probe has a built-in direction sensor, which can automatically compensate the measurement error in different impact directions. Multi-angle measurement is easy. 3. The instrument is equipped with a variety of hardness systems, including Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB) and Rockwell (HRC). Users can directly select the hardness system they want to convert inside the instrument, avoiding the tedious steps of manual table lookup. In addition, LS251D can not only test hardness, but also test material strength, with more functions. 4. The measuring accuracy of the instrument can reach ± 6HL, and the test is accurate, which can ensure that it can pass the test of the national authoritative metrology institute. Technical parameters: Probe type: D-type impact device Hardness system: HL, HV, HB, HS, HRA, HRB, HRC Measuring range: HLD (170-960); HV(83-976); HB(30-651); HRC(17.6-68.5); HS(26.4-99.5); HRB(13.5-100); HRA(60-85.8) Resolution: 1HL Measurement accuracy: ± 12 HL, ± 6 HL typical Repeatability: 6HL Display: 240 × 160 dot matrix LCD Power supply mode: 2 AA alkaline dry batteries Host size: 142 * 72 * 28 mm Probe size: 148 * 31 * 25 mm Weight: 270g
