ASTM A956 HARTIP3000 Leeb portable hardness tester with Probe E for
large work-pieces
HARTIP 3000 is an advanced hand-held digital metal hardness tester
with characters of high accuracy,
wide measuring range and easy operation. It is suitable for testing
the hardness of all metals especially
on site for large structure/assembled components. Which is widely
used in the industry of power, petro
chemistry, air space, vehicle, machine and so on.
MEASURING METHOD
The measuring principle of HARTIP series hardness testers is
defined as "the quotient of the impact body's rebound and impact
velocity, multiplied by 1000." An impact body with a Tungsten
Carbide test tip is propelled by spring force against the test
surface and then rebounds back. A permanent magnet is contained
within the impact body. When it passes through the coil on impact
device, it induces an electric voltage which is proportional to the
velocity of the impact body.
