The ITP Straight Styli Type A with Ruby Ball is a dependable, straight stylus designed for everyday metrology tasks. Built for technicians and labs, it combines a lightweight ceramic stem with a high-precision ruby contact ball for consistent measurement results.

  • Thread: M3 thread for secure, compatible mounting on common probe interfaces
  • Overall Length: 52 mm, offering balanced reach in standard measurement setups
  • Stem Material: High-performance ceramic provides low weight and exceptional rigidity to minimize probe deflection
  • Ruby Ball Size Range: Contact surface available from Ø3.0 mm to Ø8.0 mm (sizes configured per setup) for durable, precise contact
  • Configurability: Further dimensions can be requested via the configurator or by email to tailor to your system

This stylus supports stable, repeatable measurements across routine CMM tasks, with reduced tip wear and predictable contact behavior. The lightweight yet rigid construction minimizes probe loading, while the ruby ball’s hardness maintains consistent contact over long inspection campaigns. Ideal for manufacturing QA, electronics, automotive, and other precision metrology environments.
