- Material: High-performance ceramic stem delivering low weight and exceptional rigidity for steady, precise probing.

This stylus minimizes tip deflection and operator fatigue, supporting repeatable measurements across diverse materials and surfaces. The hard ruby ball resists wear for lasting accuracy, while the ceramic stem helps reduce mass-related distortion. With a 78 mm length and a standard M4 thread, it integrates smoothly into common metrology setups, making it a reliable choice for routine inspections, PCB probing, and micro-assembly tasks. If you need a different ball diameter, you can request alternative sizes via the configurator or by email to ensure the right balance of contact area and sensitivity for your workflow.
