The ITP Calibration Sphere ceramic ball is a precision reference for calibrating tactile probes and measurement devices. Manufactured as a robust aluminum oxide (ceramic) sphere, it’s built for metrology labs and industrial setups that demand repeatable accuracy.

• Ball diameter: 30 mm diameter spherical reference used for consistent contact during calibration.
• Threaded mount: M8 male thread on the top for secure attachment to probes, fixtures, or stylus holders.
• Material: Aluminum oxide (ceramic) with high hardness and dimensional stability.
• Certification: Supplied with a factory calibration certificate for traceability.
• Surface finish: Precision-ground, smooth surface to minimize contact variation during measurement.

Using this calibration sphere ensures your probing systems deliver accurate, repeatable measurements across sessions and equipment. The ceramic ball resists wear from repeated touching, helping maintain a stable reference over time. The included factory certificate provides traceability for quality management, while the M8 mounting thread enables quick, repeatable setup in a range of probe configurations—so calibration becomes a reliable step in your measurement workflow.
