Functioning similarly to the Leveridge gauge, the PDG delivers enhanced performance through a patented nonstick rack and pinion slide mechanism that provides noticeably smoother action during use.\u003c\/p\u003e\n\u003cp\u003eBuilt with components manufactured in Switzerland and assembled in Singapore, the PDG is approximately 20% lighter than the original Leveridge gauge—reducing hand fatigue during extended bench sessions without sacrificing accuracy. Measurements are read directly from the dial in 0.1 mm increments across a full range of 0.0–23.0 mm, making it suitable for a wide variety of gemstones, settings, and ring shanks.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePatented nonstick rack and pinion slide for smooth, consistent action\u003c\/li\u003e\n\u003cli\u003eApproximately 20% lighter than the original Leveridge gauge\u003c\/li\u003e\n\u003cli\u003eFunctions as a millimeter gauge, gem weight estimator, and ring size measure\u003c\/li\u003e\n\u003cli\u003eDial readout with 0.1 mm accuracy across the full measurement range\u003c\/li\u003e\n\u003cli\u003eIncludes high setting attachment for measuring raised or high-set stones\u003c\/li\u003e\n\u003cli\u003eComponents manufactured in Switzerland; assembled in Singapore\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasurement Range\u003c\/th\u003e\n\u003ctd\u003e0.0–23.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e0.1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMechanism\u003c\/th\u003e\n\u003ctd\u003ePatented nonstick rack and pinion slide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComponent Origin\u003c\/th\u003e\n\u003ctd\u003eSwitzerland\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAssembly\u003c\/th\u003e\n\u003ctd\u003eSingapore\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePresidium Dial Gauge (PDG)\u003c\/li\u003e\n\u003cli\u003eProtective case\u003c\/li\u003e\n\u003cli\u003eReference booklet\u003c\/li\u003e\n\u003cli\u003eHigh setting attachment\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Presidium","offers":[{"title":"Default Title","offer_id":43581007462614,"sku":"135.197","price":209.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/presidium-dial-gauge-pdg-with-book-high-setting-attachment-otto-frei.jpg?v=1719957785","url":"https:\/\/www.ottofrei.com\/products\/presidium-dial-gauge-pdg-high-setting-attachment","provider":"Otto Frei","version":"1.0","type":"link"}
