A new Laser Tracker field test solution for all your trackers

Following NIST guidelines, the Brunson KinAiry is a comprehensive field test for all models of laser tracker, allowing fast, regular health checks of your laser tracker in the field.

Although there is no substitute for periodic calibration of your laser tracker at the manufacturers facility, it is also important to be confident that the tracker is operating within specification on the production floor.  Comprehensive interim checks confirm instrument performance prior to critical measurements and allow users to monitor the laser trackers performance over time, ensuring that quality audit trails are maintained, particularly important when working to NADCAP and ISO accreditations.

The KinAiry consolidates various tracker specific processes into one comprehensive system check for any laser tracker model over a larger working volume than traditional methods.  Using a 2.3 metre precision reference artefact, the dedicated software guides the tracker operator through NISTs new interim field test procedure* - a set of volumetric measurements specifically designed to expose a trackers unseen geometric misalignments.  The result is a traceable, graphical analysis that quickly shows the overall health of your tracker.

* NIST’s whitepaper (NISTIR 8016) proposes a procedure for interim field testing a laser tracker's 3-D length measurement capability using a calibrated scale bar as a reference artifact. The test is specifically designed to be sensitive to uncompensated errors in length measurement caused by imperfect geometry and misalignments in the laser tracker’s construction. It is intended to be quick (less than 30 minutes) and easy to perform in the field.

The KinAiry will be also be on show at the forthcoming EPMC show, Europes largest conference and exhibition dedicated to portable metrology:
