Compact and easy to use, it is built for jewelers, gemologists, and appraisers who need a dependable screening tool at the bench or in the field. The retractable probe tip promotes correct testing technique and extends tip life, while dual indicators — continuous beep for diamond, intermittent beep for metal contact — deliver clear, unambiguous results with no waiting time between tests.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDistinguishes diamonds from all known simulants except moissanite\u003c\/li\u003e\n\u003cli\u003eNo waiting time required between tests\u003c\/li\u003e\n\u003cli\u003eContinuous beep confirms positive diamond identification\u003c\/li\u003e\n\u003cli\u003eIntermittent beep indicates probe contact with metal\u003c\/li\u003e\n\u003cli\u003eVisual light indicator accompanies audible signals\u003c\/li\u003e\n\u003cli\u003eRetractable probe tip promotes accurate technique and extends tip life\u003c\/li\u003e\n\u003cli\u003eLow battery indicator alerts before power loss\u003c\/li\u003e\n\u003cli\u003eUp to 7 hours of continuous use per set of batteries\u003c\/li\u003e\n\u003cli\u003ePowered by 3 AAA batteries (not included) or optional 120V AC adapter\u003c\/li\u003e\n\u003cli\u003eFull one-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003ePDMT-A DiamondMate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e6-1\/4\" L x 1-1\/8\" W x 3\/4\" H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\n\u003ctd\u003e3 x AAA batteries (not included) or optional AC adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery Life\u003c\/th\u003e\n\u003ctd\u003eUp to 7 hours continuous use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIndicators\u003c\/th\u003e\n\u003ctd\u003eVisual light and audible beep (continuous = diamond; intermittent = metal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProbe Tip\u003c\/th\u003e\n\u003ctd\u003eRetractable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePresidium PDMT-A DiamondMate tester\u003c\/li\u003e\n\u003cli\u003eCarrying case\u003c\/li\u003e\n\u003cli\u003eDetailed instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMoissanite shares the same thermal conductivity as diamond and will be identified as diamond by this tester.\u003c\/li\u003e\n\u003cli\u003eTo differentiate moissanite from diamond, a moissanite-specific tester or multi-function tester is required.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Presidium","offers":[{"title":"Default Title","offer_id":43581436887254,"sku":"156.751","price":122.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/presidium-pdmt-a-diamondmate-diamond-tester-otto-frei.jpg?v=1719957558","url":"https:\/\/www.ottofrei.com\/products\/presidium-pdmt-a-diamondmate-diamond-tester","provider":"Otto Frei","version":"1.0","type":"link"}
