30 kg-1 mg Single Calibration Weight, ASTM Class 5

Key Highlights

• Designed to meet NIST Handbook 44 and ASTM E617-23 specifications.

• Stainless steel construction ensures durability and corrosion resistance.

• Class 5 tolerance provides the necessary accuracy for many calibration applications.

• Sealing cavity for adjustment on most weights to maintain certified mass value.

• Nominal value clearly marked on the weight for easy identification.

• Supplied as a single, traceable calibration weight.

This single calibration weight is a fundamental tool for establishing and verifying the accuracy of weighing instruments with high capacities. Its construction from high-grade stainless steel offers excellent stability and resistance to environmental factors that could compromise its mass value over time. The adherence to ASTM E617-23 Class 5 tolerance ensures it meets recognized standards for accuracy, providing confidence in your calibration processes.

Engineered for professional use, the weight includes a sealed adjustment cavity. This design allows authorized metrology technicians to make precise adjustments to bring the weight back to its exact nominal value if necessary, supporting long-term investment protection. The clear, permanent marking of its nominal mass simplifies inventory management and prevents misidentification in the lab or warehouse, streamlining daily operations and compliance documentation.
