Mechanical Rockwell hardness tester
FEATURES
The newly designed frame provides
maximum clearance for positioning the
workpiece. A flat table is all that is needed
for mounting these testing machines.
Simple to operate
With analogue type (HR-110MR, HR-
210MR), the gauge presetting operation
is unnecessary by the adoption of an
automatic presetting dial gauge.
HR-110MR does not require a power
source, and is considered to be
environmental friendly.
The digital type (HR-430MR and HR-
430MS), with the adoption of the
automatic steering wheel brake & the
automatic load sequence, with only simple
handling test possibility.
Universal hardness tester
MZT-500
The indentation factor can be obtained, which is related to
the hardness value (partially) shown in Martens hardness
test (ISO14577) and Youngs modulus. Deformation
characteristics in the load, dwell, and unload phases are
also obtainable for use in determining properties of the
specimen material.
• Hardness tests such as Vickers and Knoop hardness tests
are supported.
• The balance lever vibration isolation mechanism reduces
the effect of external vibrations on measurements.
• Indenter indentation depth can be measured up to a
maximum of 20μm with a resolution of 0.1nm.
• Test forces between 0.1mN and 1000mN can be applied
electromagnetically for evaluation of material properties in
submicroscopic areas.
• Field-compatible form with cover for protection against
dust and wind.
