Benefits of device

  • Handheld portable 3D optical CMM
  • Compact and easy to use system
  • Optimized for measuring objects up to 3 meters wide
  • Wide range of applications
  • Comparison geometry with CAD data
  • No recalibration needed


Metronor One is the perfect replacement for your articulated arm – a handheld and portable 3D optical CMM. Metronor One is optimized for close-range measurements of small to medium-size objects up to 3 meters. Easier and less tiring to operate than articulated arms, it offers superior probing capabilities and has no need for an anchored mount or pedestal.

With the same accurate 3D volume as any standard articulated arm, you can now branch out to measure in a larger field and with easier handling.

The integrated battery and wifi pack give the Lightpen a true cable-less, joint-less design that gives you full flexibility to move and measure in your working area. This probing method provides full, unrestricted movement, just like an extension of your own arm. Comfortable to hold and fast to set-up, Metronor One fits the measurement needs of smaller objects exceptionally well.
