LS251D Portable Leeb Hardness Tester Testing Machine For MidSteel Aluminum Alloy Metal Material
LS251D Leeb Hardness Tester
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.
Leeb Hardness Tester Application
LS251D Leeb Hardness Tester is suitable for testing the hardness of materials such as steel, cast steel, alloy steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper and forged steel. The instrument can be widely used in machine tool guides, automotive chassis, heavy workpieces, mold cavities, bearings, pressure vessels and installed machinery or assembly parts and can help manufacturers to carry out product quality inspection and reasonable process analysis.

Product Features
1. Direction sensor inside the probe will compensate the measurement errors in different impact directions automatically
The instrument can measure at any angle. Featuring a built-in direction sensor, the probe can automatically compensate the measurement errors in different impact directions. Multi-angle measurement is easy
2. 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. Bwsides, it can bot only test hardness but also the strength of materials enlarging the functions.
3. 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.
4. Statistics function
The tester can automatically count the maximum value, minimum value, and average value of the lastest 9 measured values.
5. Providing Calibration Function
Users can calibrate by the standard block to eliminate the error.
