Caution
Please read this carefully first:
1. Only the special battery offered by our Company may be
used in the main body of the hardness tester. Improper
batteries might cause damages to the instrument, battery
leakage, even fire or explosion.
2. Any components of the instrument may not get
submerged in water or get exposed to rain, which could
cause a battery explosion and damage the main body.
3. Electrical shocks have to be avoided; the cabinet may
not be opened.
4. If the instrument hasn’t been used for a longer period, it
has to be stored in a cool and dry place.
1. Summarize
1.1 Measuring Principle Scope
The measuring principle of HMO Hardness Tester is
physically a rather simple dynamic hardness test:
An impact body with a hard metal test tip is propelled by
spring force against the surface of the test piece. Surface
deformation takes place when the impact body hits the test
surface, which results in a loss of kinetic energy. This
energy loss is calculated by velocity measurements when
the impact body is at a precise distance from the surface
for both, the impact phase and the rebound phase, of the
test. The permanent magnet in the impact body generates
an induction voltage in the single coil of the impact device.
The voltage of the signal is proportional to the velocity of
the impact body. A signal processing by the electronics
provides the hardness reading for display and storage.
Simply said, harder materials produce higher rebound
velocities than less harder ones (higher L- value).
HMM Hardness Tester provides a direct hardness
measurement within any particular material group (i.e.
steel, aluminium etc.). It can be used as a final test result
without conversion. However, there are established
conversions to other hardness scales in this Hardness
Tester as a comfort for our customers. These conversions
to other scales (HRC, HRB, HB, HV, HSD etc.) are
programmed into the electronics and they can be shown
directly on the display as a test result. All data is stored in
the native L scale to prevent any possible errors with
multiple conversions.

1.2. The Hardness value “L”
This term was introduced 1978 into measuring technology
by Dr. Dietmar Leeb. It contains the quotient for the impact
body’s rebound and impact velocity, multiplied by 1000.
Harder materials produce higher rebound velocity than
less harder ones. With reference to a particular material
group (i.e. steel, aluminium etc.), the L value represents a
direct hardness measurement and is used as such.
Comparison curves with other standard statistic hardness
values have been established (Brinell, Vickers, Rockwell
C, B) for the most prevalent materials, enabling the
L values to be converted into the relevant values by these
procedures. With this hardness tester, such hardness
values can directly be displayed in the hardness scales
HRC, HRB, HB, HV, HSD and tensile strength (MPa).
