Description
The ITP Straight Styli Type J with a silicon nitride ball delivers ultra-lightweight precision for metrology and probing tasks. Designed for engineers and technicians, it combines a carbon fiber stem with a durable ball tip to ensure rigidity and reliable contact on challenging surfaces.
- Length: 79 mm overall length for extended reach in tight or recessed locations
- Thread: M3 threaded connection for straightforward mounting in standard probes
- Stem material: Carbon fiber stem providing low weight and high rigidity
- Tip material: Silicon nitride ball designed for durable, smooth contact
- Configuration: Type J stylus optimized for precise measurements on untreated aluminum surfaces
- Customization: Other dimensions available via configurator or by email to tailor the stylus to your setup
This combination minimizes inertial effects during rapid probing, helping you achieve crisp, repeatable measurements with less deflection. The silicon nitride ball is particularly well-suited for scanning untreated aluminum, reducing surface marring while maintaining accuracy. If your application requires a different length or configuration, you can request alternative dimensions through the configurator or by contacting support for a tailored solution.
