The ability of a material to locally resist hard objects pressing into its surface is called hardness, which is an index to measure the softness and hardness of a material. Based on the principle of Leeb hardness measurement principle, LS251D Leeb Hardness Tester can detect the hardness of a variety of metal materials. It adopts advanced digital probe technology, and the digital signal processing is completed directly on the probe which means that the probe is not easy to be disturbed and provides excellent accuracy. The orientation sensors inside the probe will compensate the measurement errors in different impact directions automatically to ensure the accurate data. Providing a variety of hardness scales , such as Leeb scale (HL), Vickers scale (HV), Brinell scale (HB), Shore scale (HS), Rockwell scale (HRA/HRB/HRC), and they can make a mutual conversion to avoid cumbersome manual calculation. Besides the hardness, the instrument can measure the strength of the materials. The practical value of using LS251D Leeb Hardness Tester for hardness testing lies in its incomparable portable characteristics that bring users a perfect experience.
1.Using advanced digital probe technology
The tester uses advanced digital probe technology, and the digital signal processing is done directly on the probe, which is not easy to interfere with and provides excellent test accuracy
2.Direction sensor inside the probe will compensate the measurement errors in different impact directions automatically
The instrument can measure at any angles. Featuring a built-in direction sensor, the probe can automatically compensate the measurement errors in different impact directions. Multi-angle measurement is easy
3.Providing various hardness scales to switch, no more tedious manual check table
LS251D hardness tester provides a variety of hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRA/HRB/HRC) eliminating the cumbersome steps of manual table lookup. Besides, it can not only test hardness but also the strength of materials enlarging the functions
4.High-precision, ensuring that it can pass the inspection of the Chinese authoritative metrology institute
The measuring accuracy of LS251D can reach ± 6HL ensuring that it can pass the inspectionof the Chinese national authoritative metrology institute
5.QC inspection
The tester can set the upper ad lower limits and judge whether the hardness of the materials is qualified which is convienent for batch inspection
6.Statistics function
The tester can automatically count the maximum value, minimum value, and average value of the lastest 9 measured values
7.Providing Calibration
Users can calibrate the standard parts to eliminate the error
