This Rice Lake 2 lb calibration weight set is engineered to serve as a practical and authoritative mass standard for technicians and quality control personnel. The set fulfills the critical need for a portable, verifiable reference when performing in-field accuracy checks on commercial scales and non-classified balances. Manufactured from durable stainless steel, the weights are built to withstand the rigors of regular use while maintaining their stated tolerances as defined by ASTM E617-23 Class 5 specifications and NIST Handbook 44 guidelines.

Each weight in the set features a sealing cavity, which allows for professional adjustment to the exact nominal mass value. The prominent marking of the nominal value on each piece ensures quick and error-free selection during testing procedures. Optional serial number stamping provides a means for unique identification and tracking within a calibration management system, supporting quality assurance protocols. This set is fundamentally applied as a field standard for Class III devices, for the testing of general-purpose scale equipment, and for the essential practice of periodic tolerance checking to preempt measurement drift and ensure ongoing compliance.
