Can measure iron, copper, steel and other metal materials

Using advanced digital probe technology, accurate testing

Probe built-in direction sensor, automatically compensate the measurement error of different impact directions

A variety of hardness systems automatically switch, eliminating the tedious manual checking of the table
 

 

LS251D Integrated Leeb hardness tester is based on the Leeb hardness measurement principle to detect hardness and can measure hardness of various metal materials. The instrument adopts advanced digital probe technology, digital signal processing is done directly on the probe, the probe is not easily disturbed and provides excellent testing accuracy. Probe built-in direction sensor, automatically compensate the measurement error of different impact direction. The system has built-in multiple hardness systems, which can be converted between Richter (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) and tensile strength (σb) to avoid tedious manual calculations. The practical value of using the LS251D Integrated Leeb hardness tester for hardness testing lies in its incomparable portability - simple to operate, easy to carry, and allows for batch testing.

LS251D Integrated Leeb hardness tester is suitable for materials such as steel, cast steel, alloy tool steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper and forged steel, etc. The instrument can be widely used for hardness testing of materials such as machine tool rails, automobile chassis, heavy workpieces, mold cavities, bearings, pressure vessels and installed machinery or assembled parts, which can help manufacturers conduct product quality inspection, reasonable process and product quality analysis.
