Portable Measuring Arms

Portable measuring arms allow users to take the measuring task to the job rather than the traditional approach of taking the job to the CMM.

Portable measuring arms are portable measuring systems that allow the 3D measurement of part features in-situ or in locations away from the QA lab. They are fast, accurate and relatively repeatable in the the taking of measurements and when coupled with metrology software can produce full metrology reports just like a fixed CMM.

The development of the portable measuring arm technology has been significant over the last 30 years since their inception with enhancements such as absolute encoders, WiFi communications and long-life Li ION battery packs making the technology even more portable and accurate.
