Portable Hardness Tester AJH360

Product Infomation
The AJH360 model portable hardness tester 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

Portable Hardness Tester AJH360 model

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 1mmpoint 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.
