ITP Hemispherical Styli with a ceramic hollow-sphere tip are designed for precise tactile probing of coarse and rough surfaces. This stainless-steel-based stylus combines a robust body with a lightweight ceramic ball to deliver stable measurements in demanding metrology workflows.

• Base Material: Stainless steel core for rigidity, durability, and repeatable mounting in lab and shop environments.
• Ball Material: Ceramic hollow sphere ball offers low mass and inherent filtering of contact interactions on uneven textures.
• Ball Diameter: 18 mm for a wide, stable contact area that suits rough surface profiling.
• Thread Size: M3 thread ensures secure attachment to standard probe holders and measurement systems.
• Tip Geometry: Hemispherical form provides consistent contact geometry across a range of surface features.
• Precision: Machined to tight tolerances to preserve measurement integrity through multiple uses.

By combining a strong stainless-steel body with a lightweight ceramic shell, this hemispherical stylus minimizes inertial effects during scans while maintaining high-precision contact on irregular textures. It is well-suited for profilometry, tactile scanning, and surface characterization on metals, ceramics, and composites, particularly where coarse finishes or micro-roughness need reliable, repeatable measurement. The M3 threaded connector makes it easy to integrate with common metrology setups, enabling quick swap-ins without sacrificing accuracy.
