This versatile instrument distinguishes natural diamonds from lab-grown diamonds, moissanite, and common simulants—including glass, sapphire, and cubic zirconia—whether the stone is loose or mounted in any jewelry setting. With a resistive touchscreen interface, ergonomic form factor, and replaceable probe design, the OTI is built for daily professional use in bench or retail environments.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDual optical and thermal testing technology combined in a single probe\u003c\/li\u003e\n\u003cli\u003eIdentifies natural diamonds versus lab-grown diamonds, moissanite, and common simulants (glass, sapphire, CZ)\u003c\/li\u003e\n\u003cli\u003eTests both loose and mounted stones across all jewelry settings\u003c\/li\u003e\n\u003cli\u003eCompatible with colorless polished diamonds with a minimum table width of 1.6 mm\u003c\/li\u003e\n\u003cli\u003eReplaceable probe reduces downtime and extends the working life of the unit\u003c\/li\u003e\n\u003cli\u003eClear resistive touchscreen display with 6-language interface\u003c\/li\u003e\n\u003cli\u003eErgonomic, portable design suited for bench and point-of-sale use\u003c\/li\u003e\n\u003cli\u003eUser-safe UV light function shuts off automatically when not in use\u003c\/li\u003e\n\u003cli\u003eAuto shutdown and low-battery indicator for uninterrupted workflow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating Temperature\u003c\/th\u003e\n\u003ctd\u003e65°F – 80°F (18°C – 27°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage Temperature\u003c\/th\u003e\n\u003ctd\u003e50°F – 124°F (10°C – 51°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e3 × AAA lithium rechargeable or non-rechargeable batteries (not included), or USB power bank\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery Life\u003c\/th\u003e\n\u003ctd\u003eUp to 1.5 hours continuous use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProbe\u003c\/th\u003e\n\u003ctd\u003eReplaceable optical\/thermal probe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay\u003c\/th\u003e\n\u003ctd\u003eResistive touchscreen with multilingual UI (6 languages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Presidium","offers":[{"title":"Default Title","offer_id":45904574054614,"sku":"156.738","price":1565.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/156.738_thumb_c3132faa-2d63-4939-9ac5-d2ba7a3ab7c7.jpg?v=1721161214","url":"https:\/\/www.ottofrei.com\/fr\/products\/presidium-oti-diamond-tester-optical-thermal","provider":"Otto Frei","version":"1.0","type":"link"}
