Metronor SOLO Twin

The Metronor SOLO Twin system is  ideal for when your measurement object is confined in small or narrow spaces, but you still need to measure with a high degree of accuracy.

The Twin is a Metronor SOLO Probe extension that will increase your system capabilities by using two cameras right next to each other to double the field of view. The advantage is that the system can be placed closer to the measurement object even in small areas, increasing accuracy and enabling measurement in one set-up where several set-ups would otherwise have been required.

How it works

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. These applications include alignment or inspection of parallel objects such as planes or bores – e.g. in gearboxes, thrusters, turbines, or other machinery.

  • Full 70° field-of-view
  • Efficient in tight and confined spaces
  • Ideal for narrow and crowded environments
  • Operator friendly: Probing without beams, cables or arms
  • Flexible and versatile

Upgrade your system to a Metronor DUO Probe for extra capabilities. You will then be able to use your system as a SOLO Twin or as a DUO. The Metronor DUO Probe system combines large volume and increased accuracy, with the widest range of applications.

Extra Options:

An interesting option to consider if you’d like to extend your system’s applications:

  • Camera Battery Kit (114856) – measure without mains power

The Camera Battery Kit provides camera power for up to 10 hours, enabling system operation without mains power – practical where mains is not available, or to reposition the system even faster.
