Portable Hardness Tester DoHP200 digital leeb durometer for for all metals 0¢¦999HLD ¡¾ 6 HL
Principle
The tester measuring principle is physically a rather simple, dynamic hardness tester.
An impact body with a hard metal test tip is propelled by spring force against the surface of the test piece. Surface
deformation takes place when the impact body hits the test surface, which will result in loss of kinetic energy.
This energy loss is calculated by velocity measurements when the
impact body is at a precise distance from the surface for both the
impact and rebound phase of the test. The permanent magnet in the
impact body generates an induction voltage in the single coil of the
impact device. The voltage of the signal is proportional to the velocity
of the impact body, and signal processing by the electronics provides
the hardness reading for display and storage.
