The detector serves as the sensing probe that contacts the workpiece surface to measure surface texture and roughness parameters. It fits directly into the SJ-210 instrument body and enables accurate stylus-based surface measurement on the shop floor or in the field. Overall length is 61.00 millimeters with an overall diameter of 9.00 millimeters. Metrology technicians, quality control inspectors, and precision machining professionals are the primary users who install and replace this component.\u003c\/p\u003e\n\u003cp\u003eThis detector is intended for portable surface roughness measurement applications in manufacturing, machining, and quality assurance environments. It is used wherever the SJ-210 Surftest instrument is deployed, including incoming inspection stations, in-process checks on machined parts, and final surface finish verification. The compact form factor of the detector supports use in tight or difficult-to-reach measurement positions. Replacement of the detector is a routine maintenance task performed when stylus wear affects measurement accuracy or when the detector is physically damaged.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement detector accessory for the MITUTOYO SJ-210 Surftest portable surface roughness tester\u003c\/li\u003e\n  \u003cli\u003eOverall length of 61.00 millimeters supports standard probe reach for surface contact measurement\u003c\/li\u003e\n  \u003cli\u003eOverall diameter of 9.00 millimeters for proper fit within the SJ-210 instrument body\u003c\/li\u003e\n  \u003cli\u003ePackaged as a single unit for individual replacement as needed\u003c\/li\u003e\n  \u003cli\u003eCompatible with portable, field-use surface roughness measurement workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the MITUTOYO SJ-210 Surftest Portable Surface Roughness Tester.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDetector replacement on the SJ-210 should be performed by a qualified metrology technician or instrument service professional. Power down the instrument and handle the detector carefully to avoid contact with or damage to the stylus tip before and during installation. Follow the instrument manufacturer's replacement procedure to ensure proper seating and secure attachment. Dropping or side-loading the detector during installation can damage the stylus and compromise measurement accuracy.\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: SJ-210 Surftest Portable Surface Roughness Tester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 61.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 9.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches L x 4 inches W x 2 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 178-296\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558057247026,"sku":"178-296","price":813.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cd0bacff805659810ed9f98815c628a.jpg?v=1786402129","url":"https:\/\/voomisupply.com\/products\/mitutoyo-178-296-surface-roughness-gage-detector-sj-210","provider":"Voomi Supply","version":"1.0","type":"link"}
