About 18K Plumb Gold Calibration Disc for Gold Testers
18K Yellow Gold Square Calibration Disc for GemOro Gold Testers
This 18K yellow gold square calibration disc is a compact reference sample for calibrating compatible GemOro electronic gold testers. Made from true 18K yellow gold, it provides a dedicated known-metal contact surface for routine calibration, helping support consistent testing procedures in jewelry shops, gold buying counters, repair departments, and professional testing workstations.
The square calibration piece measures approximately 6.35 mm x 6.35 mm and is only 0.25 mm thick, making it easy to store with your testing supplies while still offering a flat surface for contact with the tester probe and plate. Its small, low-profile format is ideal for users who want a dedicated 18K reference piece rather than relying on finished jewelry, which may vary in actual alloy content even when marked with a karat stamp.
