It provides a maximum measurement range of 2 inches (50.00 mm) with a resolution of 0.000050 inches (0.0010 mm) and an accuracy of 0.000250 inches (0.0060 mm). The digital display delivers clear, direct readings in both inch and metric units. The center lug flat back mounting configuration allows secure attachment to magnetic bases, indicator holders, and transfer stands. This instrument is handled and calibrated by metrology technicians, machinists, and quality assurance professionals.\u003c\/p\u003e\u003cp\u003eThe CMS160713017 is suited for surface measurement, runout inspection, part comparison, and setup verification on machining centers, surface plates, and inspection fixtures. The dual-unit readout supports shops operating in both inch and metric standards. The included NIST traceability certification makes this indicator appropriate for documented quality control processes and environments subject to calibration audit requirements. The 3\/8-inch stem diameter is compatible with standard indicator holders and collet-style clamps found on most shop-floor measurement setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDigital readout with 0.000050-inch (0.0010 mm) resolution for fine measurement tasks\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.000250 inches (0.0060 mm) across the full 2-inch range\u003c\/li\u003e\n\u003cli\u003eDual-unit display reads in both inches and millimeters\u003c\/li\u003e\n\u003cli\u003eCenter lug flat back design for use with magnetic bases and standard indicator holders\u003c\/li\u003e\n\u003cli\u003e3\/8-inch stem diameter fits common collet clamps and dovetail holders\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included for calibration documentation compliance\u003c\/li\u003e\n\u003cli\u003eCR2032 battery — a widely available coin cell — powers the digital display\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 3\/8-inch stem diameter and center lug flat back configuration are compatible with standard indicator holders, magnetic base clamp assemblies, and universal dial indicator stands that accept this stem size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, metrologists, or quality technicians. Secure the 3\/8-inch stem in a collet or clamp-style holder and verify the contact point is perpendicular to the measured surface before zeroing. Avoid side-loading the stem during measurement, as lateral force can affect accuracy and damage the spindle mechanism. Handle the instrument carefully and store it protected from impact, moisture, and temperature extremes to maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement (Inch)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement (mm)\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement (mm)\u003c\/strong\u003e: 0.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Decimal Inch)\u003c\/strong\u003e: 0.000250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.0060 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution (Decimal Inch)\u003c\/strong\u003e: 0.000050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution (mm)\u003c\/strong\u003e: 0.0010 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: Digital\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Center Lug Flat Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 1.50 N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Size\u003c\/strong\u003e: CR2032\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10 inches L x 6 inches W x 1.96 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS160713017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710031462706,"sku":"CMS160713017","price":614.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf148288f45fbdd88f7603ad566aef.jpg?v=1788463344","url":"https:\/\/voomisupply.com\/products\/spi-cms160713017-electronic-drop-indicator-2in-digital","provider":"Voomi Supply","version":"1.0","type":"link"}
