It is aimed at jewelry makers, bench technicians and hobbyists who need a working probe tip for thermal conductivity testing; the single biggest reason to buy is the pen's industry-grade titanium construction and the exceptionally thin retractable tip that helps maintain consistent contact and pressure during testing, which is essential for reliable gem identification.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Compatibility:\u003c\/strong\u003e Designed specifically for use with the Presidium Gem Tester II (PGT II) and Presidium Duo Tester II (PDT II), so it fits and functions as the intended replacement probe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTitanium Construction:\u003c\/strong\u003e Built from titanium for a durable replacement option that resists corrosion and handles routine bench use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThinnest Retractable Probe Tip:\u003c\/strong\u003e The exceptionally thin retractable tip ensures consistent pressure against the gemstone and improves repeatability of contact readings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile and Reliable:\u003c\/strong\u003e Offers steady performance across common gemstones and diamonds when used with the compatible testers, providing consistent results when technique is steady.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Replacement:\u003c\/strong\u003e Intended as a direct swap for a missing or damaged probe pen, reducing downtime for testing and repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe replacement probe pen suits bench jewelers, gem dealers, and hobbyists who already own a Presidium Gem Tester II or Duo Tester II and need a like-for-like probe replacement that maintains the instrument's intended feel and contact quality.
