Metronor One


Meet Metronor One, your next handheld Portable 3D Optical CMM. As you would imagine an articulated arm, only better.

Metronor One has the same accurate 3D volume as any standard articulated arm – and more. Branch out to measure in a larger field than previously possible.

With an integrated battery and wifi pack, the Metronor One Lightpen is a true cable-less, joint-less design that gives you full flexibility to move and measure in your working area.

Metronor One offers you full, unrestricted movement, just like an extension of your own arm. Comfortable to hold and fast to set-up, it becomes the best solution for the smaller measurement needs.

Main Key Features:

– Measurement volume for high precision: 2.5 x 2.5 x 2.5m
– 3D Accuracy in 15.5m3: 0.08 mm
– System includes camera with tripod, Lightpen, laptop and transportation case and software.

 Metronor Technology  What’s Unique About It?
Metronor One uses an optical technology based on a special mathematical optical modelling method that sets it apart from other products in the market. Electro-optics and photogrammetry (the science of precisely determining the location of items based on images) let us accurately calculate where the handheld probe (called Lightpen) is located relative to the camera – both in terms of position and orientation.

The advantages? The measuring process is fast and reliable – and you can measure even in polluted environments. Just take Metronor One out of its box, turn the PC and Lightpen on, place the camera on the tripod and start measuring. Another unique feature is that we don’t have any hidden extras when it comes to pricing: your system arrives ready to use – software, laptop and all necessary parts included.

Who’s it For?
Anyone who needs to measure within a 2.5 x 2.5 x 2.5m volume. This is the true useful measurement volume. Because Metronor One has no movement hindrances, you can measure any part that fits inside this volume, including hidden, hard to reach features. You can easily measure the outside and the inside of your part.

Metronor One Lightpen Probe articulated armJust Like Using Your Arm
Our handheld Lightpen is lightweight and has no cables attached, making it very comfortable to use. There is also no movement restriction like with the traditional articulated arm, which makes operator fatigue non-existent.

Sticker-Free, Faster and Reliable
If you dislike the idea of using stickers, know that you are not alone. Measuring should be simple, quick and intuitive. That’s why we’ve been using a technology for over 20 years that doesn’t need them.

Together with active LEDs that adjust automatically to different light and measurement distances, Metronor’s unique intrinsic camera calibration method provides excellent sticker-free volumetric accuracy.



Metronor One portable CMM cameraWorried About Accuracy Loss?
Metronor One provides high volumetric accuracy throughout its measurement volume. There is no need to attach the Lightpen to something stable – it’s handheld and moves naturally with you. Accuracy deterioration, so common in articulated arms due to normal wear and especially with dust and grime in the joints, doesn’t affect Metronor One. It has no joints!

When All You Need is a Single Camera
Metronor One is a single-camera system; the camera fits in the palm of your hand and is pre-calibrated. Also, our motto is “one camera for life” – there aren’t any moving parts on our systems, all mounting fixtures are stable and there is no need for recalibration or maintenance.

Our unique one-camera concept is a true differentiator from our competitors, providing an extremely cost-effective way of supporting your company’s success. The advantages? Robustness and reliability over time, without recurring expenses.

Metronor One System articulated portable wireless arm case Working With Limited Space
The area occupied by the system is equivalent to the area occupied by the camera tripod. And unlike arms, Metronor One offers no mechanical interference with the part you’re measuring. The full system case is small and easy to carry.

As a direct benefit, you have absolute freedom of movement also in those areas that are difficult to reach, with zero mechanical interference.

Are Your Needs Constantly Changing?
When the time for expansion comes, you can upgrade Metronor One to other systems with larger volume and accuracy without losing your initial investment. There’s no need to buy a completely new solution every time your needs change.

The simplicity with which your Metronor One system can be extended and upgraded to accommodate new production challenges makes it one of the most interesting CMM options in the articulated arm market. Starting at a lower price point, you can then upgrade it at any time.
