leeb hardness tester TMT-6580 is is a portable
hardness testing set for the mobile and stationary
employment. Battery operation and compact dimensions ensure a simple
handling even in the mobile application. Due to the innovative design
with its modern load release mechanism the TMT-6580
can do fast and precise measurements of metals. With the largest
measuring range from 170 - 960L of all our gauges
it is the top product. The extra small probe with 145mm x 20mm enables
measurements in difficult accessible places, in any angle even headfirst.

details & application:
Particularly in the materials technology hardness plays a huge role.
The measured hardness of a body makes possible conclusions on its
characteristics e.g. about how quickly it breaks or is being scratched.
When using the dynamic Leeb principle, the hardness value is derived
from the energy loss of a defined impact body after impacting on
a metal sample, similarly to the Shore scleroscope. The Leeb quotient
(vi,vr) is taken as measure of the energy loss by plastic deformation:
the impact body rebounds faster from harder test samples than it
does from softer ones, resulting in a greater value 1000×vr/vi.
