Precision Weighing for Gold, Jewellery & Precious Metals

Gold trading at the retail and wholesale level requires balances with 0.1 mg or 0.01 mg readability and OIML Class I or Class II certification. A&D Japan's GH Series and GR Series analytical balances achieve 0.1 mg readability with fully automatic internal calibration, so drift caused by temperature changes in the Gold Souk environment is corrected continuously without operator intervention. The unique Super Hybrid Sensor eliminates the moving parts that cause wear in traditional electromagnetic balances, extending service life significantly in high-cycle trading environments.

Precious metal refineries and assay laboratories require even greater resolution. The A&D BM Series semi-micro balances deliver 0.01 mg and 0.001 mg readability with a built-in fanless ioniser that eliminates static charge — the primary cause of erratic readings when handling gold leaf, platinum powders, and precious metal catalysts. The large weighing chamber with interlockable slide doors accommodates crucibles and larger assay vessels without compromising draught shield performance.

For gold jewellery manufacturers, precision balances are used at every stage: incoming metal verification, alloy preparation, casting yield measurement, and final piece quality control. A&D's FZ-i/FX-i Series precision balances are a popular choice for production-floor jewellery work, combining compact footprint with 0.001 g readability and Super Hybrid Sensor accuracy at a price point suited to multi-balance manufacturing floor deployment.
