Table 1.4 - Features and applications of UCI U1 probe type
UCI U1
(98 N) 98 N
(10 kgf)
The main type of probe for
solving most problems of
hardness measurement. 10 kg
load is to be applied for
measurement (set automatically
by the probe). Low requirements
−Heat-treated and cemented details.
−Measuring in grooves, on teeth, on
radius surfaces.
−Measurement on the blades, on the
internal surface of the pipes,
openings.
UCI U1
(50 N) 50 N
(5 kgf)
The main probe type for the most
tasks of hardness measurement. 5
kg load is to be applied for
measurement (automatically
controled by the probe). Average
surface cleannes requirements.
−Heat-treated and cemented parts, for
example, shafts, turbines, gears,
teeth, welds, heat affected zones.
−Measuring in grooves, on teeth, in
grooves, on radius surfaces.
−Measurement on the blades, on the
internal surface of the pipes,
UCI U1
(10 N) 10 N
(1 kgf)
The reduced load probe is
designed to measure the hardness
of material with increased
requirements to the imprint size
(polished surfaces), to measure
the hardness of surface hardened
layers. 1 kg load is to be applied
for measurement (automatically
controled by the probe).
More sensible to the surface
cleanliness, in comparison with
U1 (50 N).
−Nitrided and cemented surface
layers of molds, stamps, stamps,
thin-walled parts.
−Bearings, lateral surfaces of saws
teeth.
−Measurement of hardness of
hardening coatings.
−Measurement on the blades, on the
inner surface of the pipes, inside the
holes.
1.5 Parts
The device consists of an electronic unit made of impact-resistant ABS plastic and placed into a
protective silicone bumper, and connected probes. The detachable connection is located on the upper
end surface of the housing; there is also a mini USB connector, which is used to connect the device to
PC or to charge the batteries. The control keyboard is located on the front panel, which also houses a
contrasting color LCD / TFT display. In the lower rear part of the device under the cover, fixed with
the threaded connection with the help of two screws, there is a battery compartment in which the
batteries are installed (Figure 1.2). In Figure 1.3, it shows the control keyboard of the device.
