Calibration weights are precision instruments designed to verify and adjust the accuracy of weighing scales and balances. To ensure durability and stability, they are made from high-quality materials such as cast iron, stainless steel, or other non-corrosive alloys. The weights are essential for calibrating scales and balances used in laboratories, manufacturing facilities, pharmacies, and other industrial settings.
