Working Principle:
The energy quotient is quoted in the hardness unit HL and is calculated from comparing the impact and rebound velocities of the impact body. It rebounds faster from harder samples than from softer ones, resulting in a greater energy quotient which is defined as 1000×Vr/ Vi.
HL=1000×Vr/ Vi
Where:
HL- Leeb hardness value
Vr - Rebound velocity of the impact body
Vi - Impact velocity of the impact body
Working Conditions:
Working temperature:- 10~+50;
Storage temperature:-30~+60
Relative humidity: 90%;
The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.
Instrument Features:
Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.
High-contrast Segment LCD ,easy to use
Support Steel ,when using D sensor to test steel,it can show HB directly.
Software calibration automatically.
100 groups (impact times 32 ~ 1) hardness
