Key Highlights

  • Designed to meet ASTM E617-13 specifications for Class 2 tolerances

  • Manufactured from high-quality stainless steel with a polished finish

  • Supplied as a single calibration weight

  • Serial numbers applied to the storage case

  • Material density of 7.95 g/cm3 for standardized buoyancy correction


This precision calibration weight serves as an essential reference standard for the routine testing and calibration of high-sensitivity analytical and micro-balances. Its construction and tolerances are rigorously aligned with ASTM E617-13 standards, ensuring it meets the stringent requirements for Class 2 weights. This compliance is critical for laboratories operating under quality systems that demand traceable and auditable measurement practices for reliable results.

The weight is machined from solid stainless steel, providing excellent resistance to corrosion and wear to preserve its mass value over time. The polished finish facilitates cleaning to prevent contamination and allows for easy visual inspection. The specified material density allows technicians to perform accurate air buoyancy corrections during calibration, a necessary step for achieving true mass accuracy in scientific and metrology applications where precision is non-negotiable.
