Description
The ITP Hemisperical Stylus combines a robust stainless steel base with a ceramic hollow-sphere probe ball, engineered for precise contact measurement on coarse and rough surface textures. Designed for metrology professionals, this stylus delivers reliable performance in demanding inspection tasks.
- Base Material: Stainless steel construction for durability, corrosion resistance, and long-term stability in laboratory and shop environments.
- Probe Ball Material: Ceramic hollow sphere provides a lightweight yet rigid contact surface with excellent dimensional stability.
- Ball Diameter: 30 mm diameter for enhanced contact coverage on uneven surfaces while preserving measurement accuracy.
- Thread Size: M3 threaded connection ensures secure, compatible mounting on standard probing systems.
- Shape: Hemispherical design offers stable contact geometry that reduces tip deflection during scans of irregular topographies.
- Intended Use: Suited for probing coarse and rough surface structures, functioning as a mechanical filter to protect the measurement system while capturing essential topography.
This stylus helps you achieve consistent, high-precision measurements on challenging surfaces. The ceramic hollow sphere minimizes mass and inertia, enabling smoother, more responsive contact during scans, while the stainless steel base provides dependable durability. Ideal for metrology setups that require reliable performance when inspecting rough textures, it supports repeatable results across multiple probes and sessions.
