Metronor DUO Portable CMM System

The Metronor DUO system combines large volume and increased accuracy, with the widest range of applications. Utilizing Metronor’s patented principle for electro-optical coordinate measurements, Metronor DUO is our most sought system, providing high-end coordinate measuring capability anywhere in the production process. Use the handheld probe to provide CMM capability – measure features such as holes, slots and edges as well as surfaces. Perform a GD&T analysis – or compare to CAD in real-time.

Compare tools, parts and assemblies to CAD or blue-print, use the LED application kit option to efficiently study stability, deformation and process repeatability, or take the system to your supplier or customer to investigate problems with interfacing parts. Metronor DUO also supports efficient alignment of objects in position and orientation (6 DOF) for example in tool building or jig-less assembly. Using two cameras and a hand-held, wireless probe, Metronor DUO provides accuracy, versatility and portability to address all your geometry-related issues.

Like all Metronor systems, it’s designed for use in rough shop floor environments and exhibits industry-leading reliability and availability. Also, at Metronor we develop modular systems. So a Metronor DUO can be easily upgraded to a Metronor DUO Split.  This boosts your investment – by purchasing a DUO you’re not only buying the tool to solve your geometry problems – it is an investment for the future. A system that can grow alongside your production.

Simple to operate, it is the most affordable high-end large-volume portable CMM system on the market. It is also extremely portable – the complete system comes in a single, roll-away transport case and weighs only 30 kilos (66 lbs).

Metronor Solo Twin System

Metronor SOLO Twin uses two separate cameras to generate each image. By effectively doubling the field-of-view, the camera can be placed closer to the measurement object, increasing accuracy and enabling measurement in one-set-up where several set-ups would otherwise be required.

During normal operation, the two cameras are mounted together on a special carbon fiber bracket ensuring optimal overlap and excellent stability.  Using a fast and simple procedure, the alignment between the two cameras can be re-determined anytime and anywhere, keeping system performance consistent over time – and after any rough handling or transportation.

Metronor SOLO Twin also enables special applications where it is critical to have two separate camera axes that are precisely known relative to each other. Such applications include alignment or inspection of parallel objects such as planes or bores – e.g. in gearboxes, thrusters, turbines, or other machinery.

Benefits

- High accuracy on large objects
- No setup – just measure
- Operator friendly: Probing without beams, cables or arms
- Tool certification within minutes
- Flexible and versatile
- Affordable capability
- Exceptional 70o field of view
- Unique solution for shaft alignment
- Ideal for narrow and crowded environments
