Precision calibration sphere made from aluminum oxide ceramic, featuring a 20 mm ball diameter and an M8 mounting thread. Ideal for metrology labs and technicians who calibrate touch probes and optical scanning systems with a trusted, certifiable reference.

• Ball diameter: 20 mm ceramic sphere for stable, repeatable contact
• Thread: M8 mounting thread for secure attachment to probes or fixtures
• Material: Aluminum oxide (ceramic) offering high hardness and wear resistance
• Certification: Factory calibration certificate included for traceability
• Applications: Designed for calibrating touch probes, CMMs, and optical measurement systems

This calibration sphere provides a reliable spherical reference that helps you verify probe accuracy, minimize measurement drift, and maintain consistent results across inspection workflows. The ceramic ball’s hardness resists wear during repeated contact, while the standard mounting thread enables quick, secure integration with a wide range of probes and fixtures. Use it to check probe offsets, validate probing strategies, and support traceable calibration records in your quality management processes.
