FH-4 Series —
Force Ranging from 10 g up to
2 kg Without Changing Weights
The FH-4 series allows testing
workpieces of a wide variety. The test
force can be selected with the help of
an easy-to-operate selector knob on
the side of the tester. Replacing any
weights is not necessary. The tester
does the full range up to 2 kg (4.4 lbs)
by just turning the selector knob to the
required force position. The test range
of the FH-4 series is quite unique for
a traditional micro-hardness tester
and is distinguished by high accuracy,
flexibility, and operational efficiency.

Digital Eyepiece Reading
The FH-4 series also has a digital
electronic microscope which enables
enhanced functionality and high
resolution readings. Obtained diagonal
measurements can be transferred
automatically and calculated to the
actual Vickers or Knoop value.
The system shows real time statistic
values and converts to Rockwell,
Brinell, Leeb and UTS (tensile strength),
making the FH-4 one of the most
advanced traditional Micro-Vickers
systems currently available.
