Description
LS251D Leeb hardness tester utilizes a D-type impact device to measure the hardness of a wide range of metal materials. The instrument adopts advanced digital probe technology to provide excellent accuracy. The probe has the built-in orientation sensor that allows measurements to be taken at all angles of 360°. Built-in multiple hardness scale, which can be converted between HL, HV, HB, HS, HRA, HRB, HRC and strength (σb). Measurement accuracy can reach ±6HL, which can ensure that it passes the test of the national authoritative metrology institute.
