itpstyli offers 4 standard reference calibration spheres with an overall length ranging from 130 to 145 mm and 4 standard sphere diameters between 15 and 30 mm.
Standard thread size is M8. If your plate or granite requires other threading, please see our adapters or consider our cost-effective customized solution.
Spheres come with a DIN EN ISO 9001-2000 certification depicting diameter and form deviation.
Each Calibration sphere comes with a certification document as per DIN EN ISO 9001-2000 which provides measurement uncertainties to the sub-micron level. The certification serial number is engraved onto the stem of the reference sphere assembly. An example of the certification is shown to the left. If a traceable certification is required, please call and we will provide a quotation for obtaining.

The standard thread base for all our reference spheres come with an M8 external thread. These robust adapters (24 mm diameter by 29 and 30 mm long) can be used to accommodate the less common M6 and M10 threaded CMM and fixturing surfaces. The adapter (and reference sphere) has wrench flats to tighten into place. For thread options other than M6, M8 and M10, please call for a quote on a customized adapter.
