Portable Hardness Tester HL-1000
Portable Hardness Tester HL-1000
Overview
A Leeb hardness tester measures hardness by assessing the rebound velocity of an impact body after it collides with a test material. The device uses a spring-loaded mechanism to propel a tungsten carbide ball (the impact body) onto the test surface at a known velocity. The ratio of the rebound velocity to the impact velocity, multiplied by a factor, determines the Leeb hardness value.
Leeb Hardness Tester model HL1000 is a unique hardness tester with so many features which no other brand can offer, the main feature is that the instrument display Hardness Value in all available scales on one screen at the same time. Hardness Probe has robust design for longer and error free performance.
