The detector contacts the workpiece surface during measurement traversal, converting surface texture variations into electrical signals that the gage unit interprets as roughness values. With a stylus tip radius of 10.00 micrometers and a maximum measurement range of 4.00 micrometers, this detector is suited for standard surface finish inspections in machining, grinding, and quality control applications. It measures 74.00 millimeters in overall length with a body diameter of 14.00 millimeters, fitting the Series 178 detector mount directly.\u003c\/p\u003e\n\u003cp\u003eThis detector is used in metrology labs, machine shops, and manufacturing quality control environments where surface finish verification is required. It is a drop-in replacement accessory intended for technicians and calibration professionals servicing or maintaining Mitutoyo Series 178 roughness tester units. Typical applications include verifying surface finish on machined components, ground surfaces, and precision-manufactured parts where Ra or Rz values must meet drawing specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned specifically for Mitutoyo Series 178 surface roughness testers\u003c\/li\u003e\n  \u003cli\u003eStylus tip radius of 10.00 micrometers for standard surface texture measurement\u003c\/li\u003e\n  \u003cli\u003eMaximum measurement range of 4.00 micrometers\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 74.00 mm overall length, 14.00 mm body diameter\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement detector for field or bench servicing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Mitutoyo Series 178 surface roughness testers and instruments within that series that accept this detector configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified metrology technician or instrument service professional. Power down the roughness tester before removing or installing the detector to avoid damage to the stylus drive mechanism. Handle the detector by the body and avoid contact with the stylus tip to prevent contamination or damage that would affect measurement accuracy. Follow the instrument manufacturer service documentation for proper seating and retention torque guidance specific to the Series 178 mounting interface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Detector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Mitutoyo Series 178 Roughness Testers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Tip Radius\u003c\/strong\u003e: 10.00 micrometers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 4.00 micrometers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 178-397-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563929993522,"sku":"178-397-2","price":2150.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4c1da2d73cb99c962217331900dd5fc.jpg?v=1786507062","url":"https:\/\/voomisupply.com\/products\/mitutoyo-178-397-2-surface-roughness-gage-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
