Why the Onyx
Set the Onyx up right beside the part, in the workshop, the measuring lab or outdoors. It keeps its accuracy in tough conditions, so it works as a portable CMM in its own right.
Kreon's most accurate arm
Very high-resolution encoders give the finest results in the range, by probe or by scanner. The 6-axis Onyx is up to 20% more accurate than the 7-axis.
Light in the hand
Light handling with flexible counterbalancing makes long measuring sessions easy. About 1 kg in the hand, 9 kg for the whole arm.
EasyClip removable handle
The handle on the 7-axis Onyx comes off in a moment, so the arm reaches into confined cavities and awkward corners.
Freedom of movement
Infinite rotation axes let you work all the way round the part without stopping to reset the arm.
QuickView screen
Battery charge, ambient temperature, arm status and the wireless link, shown on the arm itself.
Probes without recalibration
The repeatable Renishaw interface with probe autodetection means a probe change needs no recalibration.
A full shift, wireless
Wi-Fi or Bluetooth, with Ethernet where wireless is not allowed. The battery lasts 8 hours probing or 4 scanning. It swaps without switching off.
Temperature sensors
Built-in sensors compensate for thermal expansion continuously, from 10 to 45 °C. The arm is sealed to IP54. It needs no pre-heating.
6 axes or 7?
Every Onyx size comes both ways. Choose by what you will do most.
6 axes for probing
The 6-axis Onyx is made for the most demanding probing and is up to 20% more accurate than the 7-axis. At 2 m it measures to 0.023 mm E Uni.
7 axes for scanning
A seventh joint at the wrist and a handle let you guide a Skyline scanner smoothly for long sessions. The arm still probes well.
Same reach, same software
Both versions share the same measuring volumes and reach. Both run in Kreon Zenith.
Tested to ISO 10360-12
Six-axis and seven-axis arms are specified with the same tests, so you can compare their figures directly.
About ISO 10360-12Onyx probing accuracy, 6-axis
ISO 10360-12 results published by Kreon. E Uni is the worst length error across the whole volume; SPAT is the single-point articulation test.

Onyx measuring volume and reach
Every Onyx size comes as a 6-axis or a 7-axis arm. Both have the same reach. The measuring volume is the sphere Kreon specifies accuracy over; the arm reaches a little further.
| Arm size | Measuring volume (diameter) | Maximum reach (diameter) |
|---|---|---|
| Onyx-20 | 2 m | 2.42 m |
| Onyx-25 | 2.5 m | 2.92 m |
| Onyx-30 | 3 m | 3.42 m |
| Onyx-35 | 3.5 m | 3.92 m |
| Onyx-40 | 4 m | 4.42 m |
| Onyx-45 | 4.5 m | 4.92 m |
| Onyx-50 | 5 m | 5.42 m |
Choose the size by working volume and by the accuracy you need: the smaller the arm, the tighter the figures.
What people measure with an Onyx
The Onyx is for work where every micron counts: machined aerospace or automotive parts, moulds and tooling, measured to the finest tolerances on the shop floor.
Measuring to a drawing
Touch probe bores, hole positions, faces and slots. Compare them to the nominal values and tolerances on the drawing.
First article inspection
Prove a first-off meets every dimension and GD&T callout before the batch runs, then hand the customer the report.
Inspection against CAD
Align to the part, then compare probed points and features directly with the native CAD model.
On the machine
Take the arm to the machine tool and check a part before it comes off the bed, so errors are corrected while the set-up is still in place.
Fixtures, tooling and maintenance
Check jigs, welding fixtures and press tools. Measure worn parts for repair or replacement.
Reverse engineering
Add a Skyline scanner to capture whole surfaces, then rebuild the part as editable CAD with the probed features holding the precise dimensions.
Software selector
Which software do you need?
Probing on an Onyx runs in Zenith. Move to PolyWorks when your quality team already reports in it.
Kreon Zenith
Kreon's own metrology software, connected to the arm in one click. Probe and calibrate. Measure planes, circles, cylinders and slots. Align 3-2-1 or RPS, check GD&T, leapfrog across large parts, save a measuring program, then export the report as PDF or CSV.
Advanced inspection
PolyWorks|Inspector
Industry-standard dimensional inspection for portable metrology: alignment, GD&T, soft-gauging and shared reporting across a quality team.
Priced on request
Scanning as well
Add a Skyline scanner
Every Onyx can take a Skyline blue laser scanner later, with the probe still fitted underneath. Then Geomagic Design X for reverse engineering.
Priced on request
Probes, bases and stands
Priced with the arm. Tell us the parts and we will specify the right set.
Ball probes
A 6 mm ball probe comes with every arm. Balls from 1 to 8 mm, tip probes for fine detail and angled probes for awkward features.
Magnetic and vacuum bases
A 25,000 N magnetic base, vacuum base or base plate, all on the Brunson thread.
Tripods and carts
Lightweight aluminium or graphite tripods, heavy fixed or adjustable tripods, plus rolling granite carts.
Leapfrog kits
Sphere and cone kits for carrying the alignment across parts larger than the measuring volume.
Batteries and chargers
Spare lithium-ion batteries and chargers for a full shift of wireless probing.
Touch-trigger probes
Kinematic trigger probes such as the TP20, plus extensions to reach deep features.
Kreon Measuring Arm and Zenith
Two days on probing plus scanning, from probe calibration and alignment through to reporting in Zenith. For up to 3 people at our site.

Kreon Onyx questions
Which software do I need?
Kreon Zenith comes with the arm. It covers probe calibration, features, 3-2-1 and RPS alignment, GD&T, leapfrogging plus reports. It is simple to learn. If your quality team already reports in PolyWorks|Inspector we can supply that instead. Geomagic Control X and Design X come into play once you add a scanner. Kreon has long kept an open approach to measurement software, so ask us if you use another package.
Onyx or Ace?
The Onyx has higher-resolution encoders, so it is tighter at every size: 0.023 mm E Uni on a 2 m 6-axis arm against 0.029 mm for the Ace. It also adds the hot-swappable battery, the QuickView screen, the EasyClip handle and IP54 sealing. Choose the Ace when its figures meet your tolerances with room to spare.
How long does the battery last?
About 8 hours of probing or 4 hours of scanning. The battery swaps without switching the arm off, so a spare battery keeps the arm working without a break.
Can I add a scanner later?
Yes. The Onyx takes Kreon’s Skyline blue laser scanners. You can probe with the scanner still fitted. Kreon recommends the 7-axis arm for scanning, so tell us if scanning is likely and we will specify the arm to suit.
Can I try it before buying?
Yes. Bring a part and its drawing to a demonstration at our site in Cheshire, or we will come to you. We measure it on the Onyx, hand you the Zenith report and price the arm that suits it.
What training and support do I get in the UK?
Europac 3D sells and supports Kreon arms from Cheshire. Our two-day Kreon Measuring Arm and Zenith course takes up to three people from probe calibration plus alignment through to reporting. After that we give technical help by phone or email.
