This stylus supports repeatable, high-precision contact with diverse test surfaces, helping reduce measurement variability and wear on probing equipment. The ceramic stem keeps weight manageable without sacrificing rigidity, so you can work with steady anticipation of results. The ruby ball tip minimizes surface damage while delivering smooth, consistent contact across materials, making it ideal for routine metrology tasks, electronics inspection, and quality control workflows. Its M4 threaded connection and SW5.5 holder simplify integration into existing setups, and the 73.5 mm length provides a balanced, comfortable feel for both handheld use and machine-assisted measurements. For tailored ball sizes or mounting options, sizes beyond the standard are available on request.
