HEIMANN - UCI Hardness Tester SD-H3

HEIMANN - UCI Hardness Tester
Brand: HEIMANN
Model: SD-H3
Product Introduction:
For determination of copper respectively chrome hardness of rotogravure weight have the advantage that they are supposed to be non-destructive as cylinders -simple – fast – accurate.
Hardness tests in Vickers range of light the lasting surface indentation is microscopically small.
Measuring is effected by Vickers penetration procedure by electro acoustic evaluation of the indentation (UCI process).
Different instrument adjustments (calibration values, penetration times, tolerance thresholds) for various metals can be stored in the device (e. g. copper, chrome, steel, zinc). A transfer to PC via USB
interface for long-term storing is possible on a very easy way.
The measuring values and the current average value are shown simultaneously and colored (green = good; red = poor) on the display in Vickers hardness HV. Furthermore, the whole measurement-series (statistic results, single measurement values) can be displayed at a glance.
The Hardness Tester includes the following parts:
• Indicating unit with measuring and control electronics with rechargeable accumulator
• Swivelling housing holder and stable unit stand with tooth rack guide
• Measuring probe with connection cable
• Protection sleeve for the measuring probe
• Charger
• Hardness comparison plate with certificate
• Operation manual
• Communication software
Technical data (subject to technical modifications; Version 06/23):
System (Test unit and probe):
Method of testing: UCI method, correspond to DIN 50159
Test force of the probe: Motor: 3N
Test tip: Vickers diamond 136°
Measuring range: 10–2000 HV
Hardness scales: HV, HRC, HB, etc. according ASTM E140 and EN ISO 18265 for low
alloy steel
Operating time: > 10 h or > 500 measurements (dependent on system settings,
temperature and operation)
Operating temperature/Charging: 0 until +50 °C / 0 until +40 °C
Storage temperature: -10 until +60 °C
Humidity: max. 90%, not condensing
Li-Polymer-Accumulator: 3,7V / 3900 mAh
Monitor: 5'' Multi-Touch Display 1280 x 720 Pixel
Storage and data transfer: System 2 GB LPDD023 / Storage 16 GB eMMC
Q&A:
Q :Minimum thickness of the layer coating that allow for the hardness measurement ?
A:
It depends on your measuring force.
Based on a common heuristic, it's need approximately ten times coating thickness (in micron) compared to measuring force (Newton).
In case we measure with 3 Newton-probe.That means the coating should at least have 30 micron.
For copper normally have 60 and more micron so it is sufficient.
In case of chromium layer that usually only have 5-10 micron. So there is a deviation between true value and measured value
(softer copper layer under the chromium affects the measured hardness value. It is lower than true value). It is hard to generally estimate how big this effect is.
