LEEB HARDNESS TESTER

LS251D Leeb Hardness Tester

Suitable for measuring iron, copper, steel and other metal materials

Using advanced digital probe technology, test accurately
The probe has a built-in direction sensor to automatically compensate the measurement errors in different impact directions
A variety of hardness scales switchable, eliminating the tedious manual check table

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.

Applicable Materials

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.
