The ITP Straight Stylus Type A with Ruby Ball is a precision reference probe designed for tactile 3D metrology. It helps you accurately locate the position of the calibration sphere, making it a reliable choice for calibration routines in labs and manufacturing environments.

• Overall length: 63.5 mm for a compact, predictable reach in standard probing setups.
• Thread: M5 connection at the top to fit securely into common probes and holders.
• Material: Hardened stainless steel body and stem deliver high rigidity and long-term durability.
• Ball material: Ruby ball chosen for wear resistance and stable contact in tactile measurements.
• Design: Straight Type A geometry provides consistent contact geometry across measurements.

By combining a rigid stainless-steel construction with a durable ruby sphere, this stylus minimizes deflection and measurement drift during calibration tasks. The ruby ball enhances repeatability in contact with reference spheres, while the M5 thread and 63.5 mm length ensure straightforward integration into existing metrology setups. Ideal for calibration checks, sphere-based referencing, and repeatable tactile probing in precision manufacturing.
