It delivers a measurement range of 0 to 1 inch with a resolution of 0.0005 inches and an accuracy of 0.0008 inches, making it suitable for close-tolerance work on the shop floor or in an inspection environment. The unit features an LCD display and operates on a single SR44 battery, which is included. The flat back mounting style and 0.375-inch stem diameter allow for straightforward integration with standard indicator holders and magnetic bases. Machinists, toolmakers, and metrology technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drop indicator fits into dimensional inspection routines where vertical plunge-style measurement is required. It is well suited for surface plate work, fixture verification, runout checks, and part-to-part comparison tasks. The instrument supports both inch and metric measurement modes, giving it flexibility across mixed-unit shop environments. It belongs to the MITUTOYO 543 Series IDU Digimatic family and meets ANSI standards for indicator accuracy and performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0 to 1 inch (0 to 25.40 mm) with 0.0005-inch resolution\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0008 inches (0.020 mm) for close-tolerance inspection work\u003c\/li\u003e\n\u003cli\u003eLCD display for clear, direct reading without interpolation\u003c\/li\u003e\n\u003cli\u003eSelectable inch and metric measurement modes on a single unit\u003c\/li\u003e\n\u003cli\u003eFlat back design with 0.375-inch stem diameter for compatibility with standard holders\u003c\/li\u003e\n\u003cli\u003eBattery-powered with one SR44 battery included; no external power source required\u003c\/li\u003e\n\u003cli\u003eMeets ANSI accuracy standards; part of the IDU Digimatic Series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe MITUTOYO 575-123 is part of the 543 Series IDU Digimatic indicator line and is designed for use with standard indicator holders, magnetic bases, and fixtures that accept a 0.375-inch stem diameter drop indicator.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by metrology technicians or machinists using a standard indicator holder or magnetic base that accommodates a 0.375-inch stem. Secure the stem clamp firmly without over-tightening, as excessive clamping force can affect spindle movement and measurement accuracy. Before use, verify the battery is properly seated and zero the indicator at the reference datum according to the manufacturer calibration procedure. Handle the measuring spindle carefully to avoid impact, which can shift calibration or damage the internal mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 1 inch (0 to 25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0005 inches (0.010 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0008 inches (0.020 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 180 gf (1.80 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnits of Measure\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery (SR44, included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Batteries\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 543 IDU Digimatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 575-123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51562218783026,"sku":"575-123","price":263.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6d47191507a070051a1046a65330221.jpg?v=1786473374","url":"https:\/\/voomisupply.com\/products\/mitutoyo-575-123-electronic-drop-indicator-0-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
