Description

ITP Hemisperical Styli are precision probing accessories designed for metrology tasks that involve coarse and rough surface textures. Lightweight and highly controllable, they focus on delivering reliable contact data when probing challenging surfaces.

  • Base Material: Ceramic for thermal stability, low friction, and dimensional consistency during probing.
  • Probe Ball Diameter: 18 mm provides a robust contact area on textured or irregular surfaces.
  • Thread Size: M5, enabling secure mounting on compatible probe heads and fixtures.
  • Geometry: Hemispherical hollow sphere design minimizes mass while preserving precision in contact measurements.
  • Part Code: HKM518010020 for precise ordering and identification.

This stylus is well-suited for engineers and technicians conducting surface metrology on materials with coarse textures, such as castings or machined parts. The ceramic base helps reduce thermal drift, while the 18 mm hemispherical tip delivers consistent contact points across scans. The compact M5 thread ensures straightforward integration into existing probing setups, supporting repeatable measurements and improved data quality when characterizing rough surfaces.
