The \u003cstrong\u003ePresidium PDMT-A DiamondMate\u003c\/strong\u003e is a handheld diamond tester that uses thermal conductivity to quickly separate diamonds from most known simulants. 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—a continuous beep for diamond and an intermittent beep for metal contact—deliver clear, unambiguous results with no waiting time between tests.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\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\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eWhat you get:\u003c\/p\u003e\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\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\/ja\/products\/presidium-pdmt-a-diamondmate-diamond-tester","provider":"Otto Frei","version":"1.0","type":"link"}
