This 25 kg calibration weight represents the pinnacle of mass standards for high-capacity applications. Fabricated from durable, corrosion-resistant stainless steel and finished to a polished surface, it ensures minimal air buoyancy effects and long-term stability in demanding laboratory and industrial environments. Its construction and certification are meticulously controlled to comply with the rigorous requirements of ASTM E617-23 Class 1, providing the precision necessary for calibrating large platform scales, crane scales, and other high-capacity weighing systems.

The weight is an essential tool for metrologists, quality assurance professionals, and calibration technicians who require traceable and auditable mass standards. Each unit is accompanied by documentation that includes its serialized identification, ensuring full traceability to national standards. The specified density of 7.95 g/cm³ allows for precise buoyancy corrections when performing high-accuracy calibrations, making it a fundamental component for maintaining compliance and integrity in precision measurement processes.
