Professional Milligram Precision: Measures up to 20 g with 0.001 g readability for gold, gemstones, fine jewelry, coins, reloading materials, medicine, and laboratory samples.
USB-C or AAA Powered: Operate the scale with the included USB-C power cable or 2 included AAA batteries. USB-C supplies wired power and does not recharge the batteries.
Expanded Precision Tool Kit: Includes a weighing spoon and 2 tweezers for controlled transfer and placement, plus 2 x 10 g calibration weights for dependable setup.
Six Weighing Units and Useful Functions: Switch between g, oz, ct, ozt, dwt, and gn, with tare, hold, and auto-off functions for efficient measuring.
Compact and Protected: The portable design and protective flip cover help safeguard the weighing platform during storage, travel, and everyday precision work.
Customers find the scale excellent in quality, easy to use, and good value for money. They appreciate its functionality, particularly for measuring small quantities, and one customer mentions it works well for legal substances. The accuracy and calibration receive mixed feedback – while some find it super accurate, others note it’s not milligram accurate, and while the scale comes factory calibrated, many report it needs frequent recalibration. The size measurements are also mixed, with customers noting the weighing pan is very small.
