Mitutoyo 178-396-2 Surface Roughness Gage Detector

Product Description

The MITUTOYO 178-396-2 is a replacement detector accessory designed for use with Mitutoyo surface roughness and contour measuring instruments. The detector serves as the primary sensing element in surface finish measurement systems, translating stylus movement across a workpiece surface into electrical signals that the host instrument processes into roughness and profile data. Weighing 1 pound and measuring 7 inches in length, 3.5 inches in width, and 1.5 inches in height, this unit is engineered to exact OEM specifications. Installation and replacement are typically performed by metrology technicians or precision instrument service personnel.

This detector is used in precision measurement environments including manufacturing quality control labs, machine shops, and inspection departments. It is compatible with a range of Mitutoyo surface roughness and form measurement instruments. The 178-396-2 is packaged individually and sold as a single-unit replacement component for qualified service and calibration applications.
