It covers a measurement range of 0 to 2 inches with a dial graduation of 0.001 inches and a range of 0.1 inches per revolution, giving technicians fine-resolution readings across a wide travel span. Accuracy is rated at 0.004 inches. The indicator features a lug back mount, a black dial face with a 0-100 reading scale, and a built-in revolution counter for tracking total travel without losing position. A NIST Traceability Certification is included with each unit, meeting US Federal Specifications and AGD Group 2 standards.\u003c\/p\u003e\u003cp\u003eThis indicator is suited for use in precision machine shops, tool rooms, and inspection departments. Typical applications include runout checks, surface comparisons, fixture alignment, and part-to-part tolerance verification. The 3\/8-inch stem diameter and lug back design allow for flexible mounting in standard magnetic bases, surface gauge holders, and dedicated indicator arms. The universal positioning capability supports a wide range of setup orientations on mills, lathes, surface plates, and CMM fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0 to 2 inches with 0.001-inch dial graduation\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.004 inches per NIST and US Federal Specifications\u003c\/li\u003e\n\u003cli\u003eRevolution counter tracks full travel without resetting the dial reading\u003c\/li\u003e\n\u003cli\u003eLug back mount for secure, versatile positioning in standard holders\u003c\/li\u003e\n\u003cli\u003e2.2-inch diameter black dial face for easy reading at typical bench distances\u003c\/li\u003e\n\u003cli\u003eNIST Traceability Certification included for documented metrology compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/8-inch stem dial indicator holders, magnetic bases, and surface gauge arms commonly found in machine shop and inspection environments.

Secure the lug back or stem firmly before zeroing the dial to avoid measurement drift. Apply only the minimum clamping force needed to hold the indicator steady. Do not exceed the rated measuring force of 1.5 newtons on the contact point, as excessive force can affect accuracy and damage the spindle mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48 \/ M2.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 1.50 N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAGD Group\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Certified, US Federal Specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.52 x 3.35 x 2.37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 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: CMS160714030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692434882866,"sku":"CMS160714030","price":117.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bebf63e6c779d7b54db1890fba5a620.jpg?v=1788297411","url":"https:\/\/voomisupply.com\/products\/spi-cms160714030-dial-drop-indicator-0-2-in-nist","provider":"Voomi Supply","version":"1.0","type":"link"}
