This precision weight set is manufactured from austenitic stainless steel, polished to a fine finish that resists corrosion and facilitates cleaning. With a standardized density of 7.95 g/cm³, it provides exceptional performance for high-accuracy mass calibration by reducing potential error from air buoyancy, a critical factor in metrology labs. The set is supplied complete with a protective storage case, ensuring the weights remain uncontaminated and undamaged between uses, preserving their calibration integrity.
Primary applications include the calibration and verification of high-precision Class I and II analytical and precision balances. Furthermore, these Class 0 weights serve as a trusted reference standard for tolerance testing of ASTM Class 4, 5, and 6 weights, in student laboratories for educational purposes, and for rough weighing operations where a known mass is required. Each weight is marked with its nominal value, and the full set is traceable via a unique serial number applied to its case, in accordance with ASTM E617-23 guidelines.
