perating Principle
The impact body,which is equipped with tungsten carbide,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=1000X(Vb/Va)
