New QuickView screen

Clear visualisation and easy control of the arm main settings

Battery charge

Battery life:
8 hours probing
4 hours scanning.
Hot swappable battery.

Arm Status

Check the arm is 100% operational or detect potential anomalies.

Ambient temperature

Checking and monitoring of ambient temperature:
Prevent use outside normal operating temperatures (10-45°C).
Compensate for the expansion of parts during significant temperature variations.

Wifi and Bluetooth

Easily use the arm far away from the computer thanks to the integrated wireless connection.

Perfect in every detail

More ergonomic, lighter, more flexible, more robust, more reliable.

Always the best measurement results

The structure of the Onyx measuring arm, made of aluminum and carbon, is very rigid. It gives the Onyx arm remarkable measurement stability. High-resolution encoders provide high measurement accuracy.


All Kreon measuring arms are validated in accordance with ISO 10360-12 standard.

Faithful to their specifications, Kreon measuring arms can easily be integrated into a rigorous quality approach.

Comparison of Onyx measuring arms with 6 axes and 7 axes 6 or 7-axis measuring arm?

How to choose? Choose Onyx 7-axis for ergonomic scanning

Choose a 7-axis arm to scan easily and effortlessly due to its handle and ergonomic design. KREON 7-axis brings more flexibility to properly handle the scanner.
Choose Onyx 6-axis for probing and accuracy
