AJH360 Leeb Hardness Tester

Working Principle

The impact body, which is equipped with tungsten carbide, impacts into the work piece and rebounds back. The rebound and impact velocities are measured at the 1mm point from the work piece in the following way: the integrated permanent magnet will produce directly proportional voltage with the impact velocity. The Leeb hardness values are calculated by the following formula:

HL=1000×( Vb/ Va)

In Which: HL: Leeb hardness values

Vb: the voltage produced during the rebound of impact body

Va: the voltage produced during the impact of impact body


The Leeb hardness values can be converted to other hardness scales directly, such as HV, HRC, HRB, HB and HS.
