Meet the ITP Straight Stylus Type A with Ruby Ball—a lightweight, rigid probing tool designed for metrology specialists who need long-reach accuracy. With a compact 50 mm overall length and a compatible M3 XXT thread, it’s built for reliable, repeatable measurements in tight fixtures.

• Thread: M3 XXT thread compatible with a wide range of probes and holders
• Overall Length: 50 mm for extended reach in confined spaces
• Stem Material: Carbon fiber for low weight and high rigidity
• Probe Ball: Ruby ball options from Ø3.0 mm to Ø12.0 mm for precise, durable contact
• Construction: Straight design minimizes deflection and delivers consistent probing behavior
• Customization: Other dimensions available on request via configurator or email

Designed to reduce inertia without compromising stiffness, this stylus enables faster probing cycles and steadier contact on delicate surfaces. The ruby ball delivers wear resistance and stable geometry, helping you achieve repeatable measurements across sessions. For projects requiring non-standard dimensions, additional options can be configured or requested by email, ensuring the right fit for your specific metrology setup.
