ITP Calibration Sphere is a precision ceramic reference ball crafted for metrology professionals who calibrate measuring probes and fixtures. With a 15 mm ball diameter and an M8 mounting thread, it provides a reliable, repeatable reference for probe calibration.

• Ball diameter: 15 mm precision sphere designed for consistent contact and repeatable measurements.
• Thread size: M8 threaded stud for secure, quick attachment to probes and fixtures.
• Material: Aluminum oxide (ceramic) offering high hardness, wear resistance, and stable performance.
• Finish: Precisely machined surface to minimize contact deviation during calibration.
• Certification: Supplied with a factory certificate that documents dimensions and material for traceability.
• Applications: Ideal for calibrating measuring probes, reference checks in metrology labs, and fixture-based calibration setups.

Using this ceramic calibration sphere provides a stable, wear-resistant reference that helps reduce measurement uncertainty and maintain probe accuracy over time. The included factory certificate supports traceability and quality-control documentation, while the M8 mounting thread enables straightforward integration into existing calibration fixtures, helping you streamline routine calibrations and minimize downtime.
