The ITP Straight Styli – Type A with a ruby ball is a precision, straight stylus built for everyday metrology and inspection tasks. Designed for devices with M2 threaded connections, it combines a lightweight, rigid ceramic stem with a high-quality ruby contact ball to deliver reliable, repeatable measurements.

• Material: High-performance ceramic stem offering low weight and exceptional rigidity to minimize deflection during probing.
• Ball tip: Ruby contact ball available in sizes from Ø3.0 mm to Ø6.0 mm for durable, smooth, and accurate surface interaction.
• Thread: M2 thread for secure, quick attachment to compatible probing systems.
• Overall length: 51.5 mm, providing a balanced reach for standard measurement setups.
• Design: Type A straight form for straightforward probing geometry and consistent contact
• Customization: Additional dimensions can be requested via configurator or by email.

This stylus supports precise contact with minimal mass, helping to improve probing speed and measurement stability. The ceramic stem’s rigidity reduces unwanted flex under load, enhancing repeatability across multiple measurements. The ruby ball tip combines durability with low wear, extending tip life in routine calibration, surface inspection, and general metrology workflows.
