Model HRH-2100 (order code HLJ2100) is an advanced hand-held hardness tester distinguished by its high accuracy, wide measuring range, and simplicity of operation. It is suitable for testing hardness on various conditions and environments.
It is rebound principle unaffected by gravity (automatic correction) based on a spring loaded impact body which is propelled against a test piece. The forward velocity is measured and compared to the reverse velocity after rebound.
