Operating 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 )
