Portable Measuring Arms

Go-to Measurement Where It Benefits You Most

See our video.

LK Metrology launches the FREEDOM ARM range of 6 axis and 7 axis portable measuring arms – for quality control, on-machine verification, reverse engineering or 3D modelling. Available in three models, three accuracy levels and several sizes in different portable arm configurations with touch probe and laser scanner options.

  • Design for PRODUCTIVITY so manufacturing processes can stay on schedule.
  • Design for PRACTICALITY so users can measure in almost any manufacturing environment.
  • Design for FLEXIBILITY so the demands of any metrology challenge can be overcome.
  • START IMMEDIATELY  no warm-up time, no encoder referencing, no probe or laser calibrations required on start-up.
  • SWITCH QUICKLY between probe and laser without interrupting the measurement process to recalibrate and without any loss of data integrity.
  • SPIN GRIPS for easier handling of the arm on larger parts.
  • Quick Access Menu puts the most useful information right at the point of measurement, exactly where it’s needed most, in the users hand.
  • Immediate visual, acoustic and haptic feedback functions provide efficient communication to keep the process running at full speed.
  • Infinite rotation and zero-G counterbalance helps reduce user fatigue and maintains accuracy.

  • Wireless connectivity and battery power for completely portable probe and laser measurements.
  • Even the largest FREEDOM arm weighs less than 11 kilograms, making set up and repositioning a quick and easy process.
  • HomeDock and SmartLock allow the arm to be stowed and locked in place between measurements, for greater security during transport and set-up.
