Description
The ITP Straight Styli Type A with Zirconium Oxide Ball is a precision probing stylus designed for metrology professionals who work with ferrous components. It combines lightweight ceramic construction with a hard zirconia tip for reliable, everyday use in demanding measurement tasks.
- Thread: M3 threaded connection for quick, secure mounting to standard probe heads.
- Tip Material: Zirconium oxide ball delivers high hardness and excellent wear resistance, similar to ruby surfaces.
- Stem Material: High-performance ceramic provides low weight and exceptional rigidity to minimize flex during scans.
- Overall Length: 52 mm, offering versatile reach in tight or standard measurement setups.
- Ideal Application: Surface scanning and probing of cast iron components where durable, stable contact is essential.
The combination of a zirconium oxide tip and a ceramic, lightweight stem reduces tip wear and improves measurement stability across repeated scans. With a rigid profile and precise M3 attachment, this stylus helps deliver consistent contact data, shorter inspection cycles, and better repeatability when evaluating hard metals like cast iron.
