The Mitutoyo 178-393 is a precision replacement detector designed specifically for measuring surface roughness in extra-small holes and confined spaces. Compatible with SJ-410 and SJ-310 Surface Roughness Tester models, including Standard, Retractable, and Transverse Drive Unit configurations.

Key Specifications:
