Description
ITP Hemispherical Styli are precision probing accessories designed for challenging surface textures. With a ceramic probe ball and sturdy stainless steel base, they deliver reliable contact when measuring coarse and rough surfaces.
- Shape: Hemispherical hollow sphere for stable contact on textured surfaces
- Base Material: Stainless steel for durability and structural rigidity
- Probe Ball Material: Ceramic for wear resistance and consistent measurements
- Thread Size: M5 for secure attachment to compatible probes
- Ball Diameter: 30 mm to match the contact footprint on rough textures
- Application: Serves as a mechanical filter during probing of coarse or uneven surface structures
This hemispherical stylus helps reduce measurement noise on rough textures by acting as a controlled contact point, preserving geometric fidelity while smoothing contact dynamics. The hollow design keeps the assembly lightweight for responsive probing, and the ceramic ball offers long-lasting wear resistance. Paired with a robust stainless steel base and standard M5 threading, it integrates smoothly into typical metrology setups, making it a reliable choice for quality control, surface analysis, and industrial measurement workflows.
