Mitutoyo 178-296 Replacement Low-Force Detector for SJ-210/SJ-310 Surface Roughness Tester

The Mitutoyo 178-296 is a precision replacement low-force detector designed for use with SJ-210 and SJ-310 surface roughness testers, compatible with both standard and retractable drive unit models. This detector features a 0.75mN stylus force with a 60-degree, 2-micron radius diamond stylus tip, making it ideal for measuring delicate surfaces without damaging the workpiece.

Key Specifications:

• Stylus force: 0.75mN (low-force application)
• Stylus tip geometry: 60-degree conical diamond with 2-micron radius
• Compatible with SJ-210 and SJ-310 surface roughness measurement systems
• Works with both standard and retractable drive unit configurations

This low-force detector is essential for accurate surface texture measurement in quality control, manufacturing, and inspection applications. The reduced stylus force minimizes the risk of surface damage when testing soft materials, thin coatings, or finely finished components while maintaining measurement accuracy and repeatability.
