Mitutoyo 178-386 Standard Detector 4mN Measuring Force 5μmR Stylus

The Mitutoyo 178-386 is a precision standard detector designed as an optional accessory for Surftest SJ-210 and SJ-310 surface roughness testers. This high-quality detector features a 4mN measuring force and a 5μmR/90° tip radius stylus, making it ideal for accurate surface profile measurements across a wide range of materials and applications.

Key Features:

• Compatible with Surftest SJ-210 and SJ-310 surface roughness measurement systems
• 4mN (millinewton) measuring force for consistent, reliable contact with test surfaces
• 5μm radius stylus tip with 90° angle for precise surface profile tracing
• Dedicated design for use with transverse tracing drive unit
• Standard detector configuration suitable for general-purpose roughness testing

This detector is an essential component for maintaining measurement accuracy and repeatability in quality control, manufacturing, and metrology applications. The carefully calibrated measuring force ensures minimal surface deformation while maintaining adequate contact for accurate readings.
